Abstract: A technology is described for a dual path repeater configurable for a split mode and a multiple input multiple output (MIMO) mode. The dual path repeater can comprise first and second server ports and first and second donor ports. Four amplification and filtering paths are communicatively coupled between the ports. Each amplification and filtering path include a software defined filter (SDF). The SDFs are configured to filter the same 3GPP bands to provide MIMO communication or the first SDF and the second SDF are configured to filter different bands to enable the dual path switchable repeater to provide split mode communication on multiple TDD/FDD bands.

Abstract: A display may include an optical emitter that emits infrared light, a first coupler that couples the infrared light into a waveguide, and a second optical coupler that couples the infrared light out of the waveguide and towards the eye box. The infrared light may reflect off an eye as reflected light. The second optical coupler may couple the reflected light into the waveguide and the first optical coupler may couple the reflected light out of the waveguide and towards a camera for performing gaze tracking operations based on the sensor data. The display may sequentially illuminate different regions of the eye with the infrared light at different times using a scanning mirror, an array of light sources, or a wavelength-adjustable light source and gratings. This may minimize infrared light scattering, which minimizes background generation and maximizes signal-to-noise ratio for gaze tracking operations.

Abstract: A system and method for a fantasy sporting event game that reduces the requirement that the game player be skilled in the sport, or have knowledge of the sport. The method resolves the competition with a single actual sporting event as opposed to a season. The fantasy team players, chosen from players participating in the live sporting event, are randomly assigned to the fantasy teams. Team owners sign on after a live sporting event has been selected. Game players are then each assigned team members to fill out their rosters. An actual live player may be assigned to more than one team. Likewise, the fantasy teams established need not contain an actual live player from each of the positions for the particular sporting event. Variations as to the number of players on a fantasy team and the duration of the one-game time period are anticipated.

Abstract: The light energy necessary for the precure process is held by the RFID at the holographic memory. The controller acquires the light energy corresponding to the temperature of the recording position detected by the temperature sensor out of the precure information acquired by the RFID reader. The exposure time (light emitting time of LED) Te in the precure process is calculated based on the calculating equation Te (sec)=En (joule)/Pd (watt) from the energy En and the intensity Pd of light irradiated onto the recording position detected by the light detector.
