Abstract: Systems and methods are disclosed that include an electronic device and an activation device. The electronic device includes a battery compartment having a battery storage section and a battery engagement section. The battery engagement section includes battery contacts. The electronic also includes a battery disposed in the battery storage section of the battery compartment. The battery moves from the battery storage section to the battery engagement section in response to an activation event to place the battery in electrical contact with the battery contacts. The activation device includes an activation element configured to generate the activation event.

Abstract: An adapter is disclosed herein. The adapter comprises a base, at least one retention element, a biased latch, a handle, and a switch. The base has a first surface and a second surface opposite the first surface. The first base surface is configured to receive a first surface of a mobile computing device. The at least one retention element is positioned on a front end of the base and is configured to receive a first end of the mobile computing device. The biased latch is positioned on a rear end of the base and is adapted to attach a second end of the mobile computing device. The handle is positioned on the second base surface and the switch is positioned on the second base surface adjacent to the handle. The switch is mechanically linked to the biased latch, and the biased latch is configured to release the mobile computing device from the base when the switch is actuated.

Abstract: A rotatable connection assembly for a payment module is disclosed herein. The connection comprising a module sled having a module sled connection; a mobile computer mount having a mobile computer connection; a cable between the module sled connection and the mobile computer connection; a rotatable connection assembly disposed between the module sled and the mobile computer mount such that the module sled rotates with respect to the mobile computer mount between a first position and a second position.

Abstract: Disclosed is a contact lens comprising an optical region including a first area, a second area and a third area, concentrically arranged in such order from a lens center. The first area includes a correction zone having a nearsightedness correcting power. The second and third areas each include at least two defocusing zones and at least one correction zone, wherein the at least two defocusing zones and the at least one correction zone are alternatively arranged. The second area has a first power difference of ?2.00 to ?5.00 D, the third area has a second power difference of ?3.00 to ?10.00 D, and the second power difference is equal to or more negative than the first power difference.

Abstract: A human computer interaction system and a human computer interaction method are provided. The human computer interaction system includes a first sensor, a second sensor and a processor. The processor obtains first motion sensing data of the first operating portion from the first sensor, obtains second motion sensing data of the second operating portion from the second sensor different from the first operating portion, and determines an event according to both the first motion sensing data and the second motion sensing data. Accordingly, a hybrid motion tracking method for multiple operating portion of the user is provided.

Abstract: A wearable electronic device is provided. The wearable electronic device includes a wireless communication unit, a processing unit, a watch interface and a display unit. The wireless communication unit performs wireless communication with a portable electronic device. The processing unit synchronizes with the portable electronic device to retrieve event data from the portable electronic device through the wireless communication unit, wherein the event data comprises a plurality of events and time information corresponding to the events. The watch interface has a dial. The processing unit controls the display unit to display a color bar surrounding the dial, wherein the color bar includes a plurality of sections to display durations of the events based on the time information. When the processing unit determines that a time-based condition or a location-based condition of the events is met, an intimating signal is generated under the control of the processing unit.
