IPC: G02F1/133
Filed: 1986-01-07
Abstract: PURPOSE:To obtain a liquid crystal light valve which has superior contract and secure sufficient brightness on a screen by bringing a cooling panel which has cooling liquid charged between two transparent substrates into contact with a liquid crystal panel. CONSTITUTION:A package substrate 60 is a circuit board, the lower substrate 61 of the liquid crystal panel is guided in a recessed part cut to the same thickness of the lower substrate 61, and the liquid crystal panel is composed of a polarizing plate 63 of almost the same size with the upper substrate 62. The polarizing plate is brought into contact with the lower substrate 65 of the cooling panel by a connector 64 so that the cooling panel contacts the liquid crystal panel. The upper substrate 66 of the cooling panel is surface where light source light is incident, so the surface is provided with a nonreflective coating to increase incidence efficiency. Guest-host type liquid crystal is charged as the cooling liquid of the cooling panel and electricity is applied to an upper and a lower solid electrode to form a liquid crystal having electrooptic effect and also realize the liquid crystal light valve which has an incident light dimming function and a cooling function.

Title: Dynamic control of transmitting power at a transmitter and attenuation at a receiver.
Inventor: UNO BORG LARS
IPC: H04B1/04
Filed: 1994-05-13
Abstract: A communications system includes a receiver and a transmitter for transmitting a communications signal to the receiver. The transmitter adjusts its transmission power level in response to receiver power control signals transmitted by the receiver. The receiver includes an attenuator for attenuating the received communications signal, and measurement circuitry for measuring the signal strength of the attenuated signal. The measured signal strength is coupled to an attenuator controller and to a transmission power controller. The attenuator controller and the transmission controller adjust, respectively, receiver attenuation and transmitter power level so as to optimize system performance. This may include keeping the attenuated signal within the dynamic range of the receiver. This may also include eliminating disturbance signals by adjusting receiver attenuation to produce an effective dynamic range for receiving only signals having a signal strength level that is higher than the disturbance signal strength level, while at the same time increasing the transmission power level to keep it within the effective dynamic range of the receiver. The disturbance signal may be detected as an increased bit error rate of the received communication signal. The apparatus and method may also be applied to systems in which a plurality of receivers are coupled to a common antenna through a receiver multicoupler.
