Patent number: 7522233Abstract: In a display device, a backlight unit emits light forward. Picture elements are arranged in columns and rows to define a picture element plane and each of the picture elements has a transmitting region to transmit light coming from the backlight unit. Collecting elements are arranged in front of the backlight unit to transmit and collect the light on the picture element plane. Each collecting element is associated with the transmitting region of one of the picture elements. The light transmitted through each collecting element forms a beam spot on the picture element plane.

Patent number: 7519107Abstract: In a CDMA receiving apparatus, a delay profile using a desired constraint length is generated by a delay profile generating unit from received signal wave-form data recorded on a received signal wave-form buffer unit. Several demodulation paths are selected at peak position of the delay profile by the path search unit. Demodulation symbols which are generated from received signal wave-form data of each demodulation path by the channel demodulating unit are brought into in-phase by an adjustment angle which is obtained by the channel estimating unit. If the reception quality which is measured by the reception quality measuring unit is lower than a predetermined value for a combined demodulation symbol which is combined by a RAKE unit, the combination of said selected demodulation paths or the constraint length is changed to repeat the demodulation operation of the same received signal wave-form data.Type: GrantFiled: July 20, 2004Date of Patent: April 14, 2009Assignee: Sharp Kabushiki KaishaInventor: Shiro Sugahara

Patent number: 7518626Abstract: In this light beam synchronization detector, an enable circuit 34 outputs a first control signal Se1 to an output circuit 35 when at least one of the absolute values of a voltage signal V1 from a first amplifier 31 and a voltage signal V2 from a second amplifier 32 exceeds the absolute value of a threshold voltage ?Vth, thereby putting the output circuit 35 into an operative state. The enable circuit 34 outputs a second control signal Se2 to the output circuit 35 when both the absolute values of the first output voltage V1 and the second output voltage V2 are equal to or lower than the absolute value of the threshold voltage ?Vth, thereby putting the output circuit 35 into an inoperative state.
