Abstract: Computing systems and methods are provided for detecting skin conditions of humans. A computing device can authenticate a user via a fingerprint scan of a first skin region of the user using a three-dimensional (3D) sonic sensor. The device can generate a three-dimensional (3D) volumetric sonic measurement of a second skin region of the user based at least in part on one or more sonic pulses of the three-dimensional sonic sensor. The device can input data indicative of the 3D volumetric sonic measurement into one or more machine-learning models, generate one or more skin cancer condition identifications associated with the second skin region of the user based on one or more outputs of the one or more machine-learned models, and provide one or more outputs including the one or more skin cancer condition identifications associated with the second skin region of the user.

Abstract: A description of one or more items identified by a buyer for purchase is received. Each item is represented as an object in a hierarchical data structure. A processing strategy is executed on the hierarchical data structure to generate purchasing information describing a purchase transaction involving the items. A display preprocessing strategy is executed to create display information describing a display of the generated purchasing information. The display information is transmitted to the buyer for generation of the display using the display information.

Abstract: A keypad mouse computer peripheral device of the present disclosure includes a housing on top of which is located a keypad having a number keypad. The input device has at least one clicker button operable by a user's thumb while the user's hand rests on a provided palm rest or wrist rest. Force exerted by the base or palm portion of an operating hand moves the present input device which permits the index, middle and ring fingers to be located on the 4, 5, 6 key positions of the number keypad. This maintenance of the resting or home position even while the user is engaged in movement of the present keypad mouse permits easy and fast entry of numbers. A position sensor on the bottom surface of the housing of the disclosed keypad mouse detects relative location information for positional information input for a computer's graphical user interface.

Abstract: A keypad peripheral device of the present disclosure includes a housing on top of which is located a keypad having a numeric keypad, function keys, Tab key, and right click key. The function keys may be F2 or F4 or both F2 and F4. Alternatively, F8 function key and/or directional keys may additionally be included. The present keypad peripheral device may further include the following keys: home, end, page up, and page down keys, and alternatively further comprise a back space or delete key or alt and control keys. Alternatively, at least one key of the keypad has a height that is less than at least another key of the keypad and this may be to avoid inadvertent contact with a finger or base of an operating hand. Further, an on/off switch may be provided on a bottom surface of the housing of the present computer peripheral device.
