摘要： The present invention relates to a method of channel estimation comprising two major steps. The first step is the least-squared and minimum mean-square error (MMSE) estimations on the pilot resource elements to generate the channel response estimates at the predefined pilot locations. The second step of the channel estimation, which utilizes the results from the first step to compute the channel response estimates for the remaining resource elements, comprises the following three operations: (i) averaging of each pair of adjacent pilot resource elements in the frequency direction to obtain the channel response estimate of the resource element in the middle of those two pilot resource elements; (ii) MMSE interpolation in the time domain for all the sub-carriers containing pilot signals; and (iii) linear interpolation in the frequency direction for all the sub-carriers not containing any pilot signals.

摘要： The present invention provides an omnidirectional wind collection apparatus. The wind collector includes an outer housing with a peripheral wind inlet circumferentially formed therein. An inner housing disposed within the outer housing has an inner surface with a first opening at a lower end thereof to guide the collected wind to a smaller second opening at the top end. The inner surface is curved between the bottom and top openings to form a progressively narrower passage. The configuration of the inner surface creates a Venturi effect such that the wind is accelerated toward the second opening. A wind pass-through portion is formed above the second opening in the inner housing. Based on the Bernoulli effect, the passage of uncollected wind through this portion creates a low pressure region that expedites flow of collected wind through the first and second openings of the inner housing.

摘要： A head-up display including a hybrid illumination system is provided. A light mixing unit provides a substantially homogenous light source to a reflective display unit. A concentrating optics unit collects ambient light and directs it towards the light mixing unit. At the same time, an electrically-powered light source emits light which is directed towards the light mixing unit. One or more optical elements direct the ambient light and the light source light into the light mixing unit for homogenization. A condensing unit receives the homogenized light mixture and outputs the condensed light to a polarizing beam splitter. A reflective display modulates the light from the polarizing beam splitter with information from a source of electrical information signals back towards the polarizing beam splitter. A projection unit projects the modulated light to create an image on a windshield.

摘要： The present invention provides an ink jet printable phosphor ink composition for LED packaging that enables precision control of the amount and position of phosphor layers on the LED device or the LED device packaging. The ink includes both a UV-curable resin component and a thermally curable resin component. A phase-separation component prevents phase separation of the UV-curable resin component and the thermally curable resin component. Phosphor particles on the order of less than approximately 2 microns are uniformly dispersed throughout the ink composition. The phosphor ink composition is deposited through either thermal or piezoelectric ink jet printing; a thin layer is deposited in a desired pattern. UV curing (and, optionally, thermal curing) is used to fix each layer followed by subsequent deposition and curing. In this manner, undesirable phosphor settling does not occur and layers are selectively built up to form precise phosphor distributions.

摘要： A structure is provided to create an efficient light pattern conversion from a narrow angular light beam pattern of a light emitting source to a wide angle light intensity distribution for an omnidirectional lighting assembly. A heat conductive substrate includes an LED array with at least one central and at least one surrounding LED. A hollow light diverting component is positioned over the LED array; a central LED is within the hollow component while surrounding LEDs are positioned outside. Light emitted by the central LED is reflected off inner surfaces of the hollow component to be discharged from an upper opening. The outer component surface is configured to reflect light from the surrounding LEDs in azimuthal and circumferential directions towards a region below the upper opening. In this manner, plural LEDs are used to form a wide angle emission pattern suitable for use in conventional light bulb replacement devices.
