[0025] Any reference in the specification to a method should be applied mutatis mutandis to a system capable of executing the method.

[0026] Any reference in the specification to a system should be applied mutatis mutandis to a method that may be executed by the system.

[0027] There is provided a jacket that includes one or more medical modules. The one or more medical modules may be integrated with the jacket or be detachably connected to the jacket.

[0028] The jacket may at least partially surround a smartphone.

[0029] The j acket may include a first portion (such as a rear portion) that may contact the backside of the smartphone. The first portion may allow the smartphone to be contactless charged by a wireless charger (usually by inductance) - and should not mask such contactless charging. This may be obtained by using a first portion that does is not thick (for example may be thinner than 0.5 centimeter) and is not made of inductance charging blocking materials - it may, for example be made of metal. Alternatively - the first portion may include metal parts- but the metal parts may cover only a part of the back of the smartphone - or may include apertures or include a mesh- that will enable the inductance based charging.

[0030] The jacket may include a second portion (such as a movable portion) that may face (or be proximate to) the screen of the smartphone - when the jacket is closed - thereby protecting the screen of the smartphone.

[0031] The second portion may be coupled to the first portion via an interface (also referred to as intermediate portion. [0032] The second portion may be moved (for example by rotation or any other movement) thereby facing the first portion of the jacket (and the back of the smartphone).

[0033] The second portion may at least partially conceal the medical module. Parts of the medical module that should not be concealed (for example - sensors that should touch a person and/or have a clear field of view directed to the person) should not be permanently concealed by the second portion. Such parts may be temporarily sealed or be exposed. These parts may be exposed when the jacket is closed (not face the screen of the smartphone) or may be concealed (and may, for example, face the screen of the smartphone - when the jacket is closed. These parts may include electrodes, conductors that are electrically coupled to the electrodes, optics that follow a radiation light or precede a detector, and the like.

[0034] Concealing the medical module when the jacket is exposed may protect the medical module and also prevent any inconvenience resulting from the exposure of the medical module to the public.

[0035] Smartphones are equipped with backside cameras and other knobs, buttons or components that are positioned at the back of the smartphone. Medical devices that are permanently connected to the back of the smartphone should not cover these components and should be tailored according to the exact design of each smartphone.

[0036] Positioning the medical module within the jacket - without permanently connecting the medical module to the back of the smartphone - allows to design the medical module regardless of the exact design of the smartphone - and even allow the medical module to conceal one or more of these elements - during the medical measurement process.

[0037] The jacket in general and the second portion may include one or more chambers, one or more pockets and/or one or more compartments for holding the one or more medical modules. The one or more chambers may include one or more openings for inserting the one or more medical modules and/or for exposing parts that should be exposed, at least during a medical testing period. An opening may remain open or may be closed by any closing elements such as a zipper, or any fastening element.

[0038] The second portion can be made of plastic, of cloth, of metal and the like.

[0039] The jacket can store, in a convenient manner, more medical modules and/or medical modules of larger size than is possible by merely connecting the medical modules to the back of the smartphone. [0040] The jacket may be detachably connected to the smartphone, may partially surround the smartphone, and the like. For example - the first portion hold the smartphone, may surround the back of the smartphone and at least a part of sidewall of the smartphone thereby connecting the jacket to the smartphone. The jacket or the first portion may be elastic and slightly smaller than the smartphone - and inserting the smartphone into the jacket or the first portion may keep the smartphone within the jacket of the first portion.

[0092] Any arrangement of components to achieve the same functionality is effectively "associated" such that the desired functionality is achieved. Hence, any two components herein combined to achieve a particular functionality may be seen as "associated with" each other such that the desired functionality is achieved, irrespective of architectures or intermedial components. Likewise, any two components so associated can also be viewed as being "operably connected," or "operably coupled," to each other to achieve the desired functionality.

[0093] Furthermore, those skilled in the art will recognize that boundaries between the above described operations merely illustrative. The multiple operations may be combined into a single operation, a single operation may be distributed in additional operations and operations may be executed at least partially overlapping in time. Moreover, alternative embodiments may include multiple instances of a particular operation, and the order of operations may be altered in various other embodiments.

[0094] Also for example, in one embodiment, the illustrated examples may be implemented as circuitry located on a single integrated circuit or within a same device. Alternatively, the examples may be implemented as any number of separate integrated circuits or separate devices interconnected with each other in a suitable manner. [0095] Also for example, the examples, or portions thereof, may implemented as soft or code representations of physical circuitry or of logical representations convertible into physical circuitry, such as in a hardware description language of any appropriate type.

[0096] Also, the invention is not limited to physical devices or units implemented in nonprogrammable hardware but can also be applied in programmable devices or units able to perform the desired device functions by operating in accordance with suitable program code, such as mainframes, minicomputers, servers, workstations, personal computers, notepads, personal digital assistants, electronic games, automotive and other embedded systems, cell phones and various other wireless devices, commonly denoted in this application as 'computer systems'.

[0097] However, other modifications, variations and alternatives are also possible. The specifications and drawings are, accordingly, to be regarded in an illustrative rather than in a restrictive sense.

[0098] In the claims, any reference signs placed between parentheses shall not be construed as limiting the claim. The word 'comprising' does not exclude the presence of other elements or steps then those listed in a claim. Furthermore, the terms "a" or "an," as used herein, are defined as one or more than one. Also, the use of introductory phrases such as "at least one" and "one or more" in the claims should not be construed to imply that the introduction of another claim element by the indefinite articles "a" or "an" limits any particular claim containing such introduced claim element to inventions containing only one such element, even when the same claim includes the introductory phrases "one or more" or "at least one" and indefinite articles such as "a" or "an." The same holds true for the use of definite articles. Unless stated otherwise, terms such as "first" and "second" are used to arbitrarily distinguish between the elements such terms describe. Thus, these terms are not necessarily intended to indicate temporal or other prioritization of such elements. The mere fact that certain measures are recited in mutually different claims does not indicate that a combination of these measures cannot be used to advantage.

[0099] While certain features of the invention have been illustrated and described herein, many modifications, substitutions, changes, and equivalents will now occur to those of ordinary skill in the art. It is, therefore, to be understood that the appended claims are intended to cover all such modifications and changes as fall within the true spirit of the invention.
