Abstract: A display system for sensing a finger of a user applied to the display system includes a display panel; a sensor for sensing the finger; a sensing light source configured to emit a first light having a first wavelength W1; and a reflective polarizer disposed between the display panel and the sensor. For a substantially normally incident light, an optical transmittance of the reflective polarizer versus wavelength for a first polarization state has a band edge such that for a first wavelength range extending from a smaller wavelength L1 to a greater wavelength L2 and including W1, where 30 nm?L2?L1?50 nm and L1 is greater than and within about 20 nm of a wavelength L3 corresponding to an optical transmittance of about 50% along the band edge, the optical transmittance has an average of greater than about 75%.

Abstract: A mobile device case for a mobile device having a first battery to operate, said mobile device case comprising of a housing to receive said mobile device; a second battery being embedded in said housing; a pair of thermometers embedded in said housing to monitor the temperature of said first battery and ambient surrounding said housing; a GPS device to determine the location of the mobile device case; an electronic communication means to communicate with a plurality of satellites to send and receive a data related to the location of the mobile device case; and a processor to process the functionality of said second battery, said thermometers, said GPS device and said communication means and switch between said second battery and said first battery; whereby the processor switches the power source of the mobile device from said first battery to said second battery when said first battery is dead.

Abstract: A system for improving management and delivery of database management functions (also know as APIs) to customers. Additionally, the system encompasses methods for simplifying delivery and use of standardized database management functions by users while improving management and control of the standardized database management functions (API's) through unique methods of encryption, decryption and execution management.

Abstract: A bracket for mounting an optical component to a circuit board. The bracket comprises a bracket body member having a board contacting surface extending in a first plane defined along its board contacting side. A component mount is defined along the body member with a termination surface extending adjacent the board contacting side in a plane recessed from the first plane.
