In a wireless base station comprising a center unit, and a remote unit provided with an array antenna and connected to the center unit through an optical fiber, the center unit outputs to the optical fiber a transmission signal in a base band state prior to array processing, the remote unit performs the array processing of transmission signals in accordance with array weights and converts the transmission signals into RF signals, thereby to localize the compensation for transmission signal deviations occurring among the antenna elements on the remote unit side.

An unmanned aerial vehicle (UAV) having at least one sensor for detecting the presence of a survivor in a search and rescue area. The at least one sensor is preferably an ultra-wide band (UWB) transceiver sensor. The UAV includes a UAV data link transceiver for wirelessly communicating information concerning the survivor to a command center.

An apparatus and method are disclosed for maintaining free buffer information for a network switch. A first Random Access Memory (RAM), located on the network switch, functions to store values that indicate whether or not free buffers, located in a second RAM, are available for storing received data frames. An input logic is provided for placing values in the first RAM to indicate which free buffers are available for storing the data frames. When free buffers are required to store data frames, the output logic searches the first RAM and locates values that indicate available free buffers in the second RAM. The output logic then generates buffer pointers that address the locations of the free buffers in the second RAM. The buffer pointers that are generated are stored in a small capacity queue on the network switch to provide immediate availability to free buffers.

Preferably, the amount of the coloring agent is at most approximately 0.03 percent by weight and the implant is sterilized by radiation.

A system and method for utilizing a humidity sensor with an internal combustion engine of a vehicle is described. Specifically, information from the humidity sensor is used to adjust a desired air-fuel ratio to reduce engine misfire while improving vehicle fuel economy. Further, such information is also used to adjust timing and/or lift of the valve in the engine cylinder. Finally, diagnostic routines are also described.

A body bias control system allows for independent design of a functional module, thereby reducing the burden of designing the module. The body bias control system provides a switch circuit having an area in which the body bias is controlled independently of its outside portion, for controlling the supply of body bias in the vicinity of the area. Preferably three types of switches are provided for switching the body bias to suitable levels for a standby mode, a mode of normal operation and a mode of high-speed operation.

A microelectromechanical modulation device comprising: a movable portion, which is supported to be elastically and bi-directionally displaced and which has a modulation function; and a plurality of driving sources operative to apply a physical action force to said movable portion, wherein when said movable portion is displacement-driven in a first direction, a physical action force for suppressing oscillation of said movable portion is applied to said movable portion in a second direction different from the first direction by said drive sources while said movable portion is transited in the first direction.

A method for effecting synchronous pulse generation for use in variable speed serial communications is provided. The method includes the steps of obtaining a communication link speed; generating a difference signal representing a signal level difference between at least two data stream signals; providing a clock signal; providing a counter; defining a sample count value of the counter using the communication link speed; incrementing the counter in relation to the clock signal; and determining whether a current count value of the counter corresponds to the sample count value. If the current count value corresponds to the sample count value, then the method performs a step of generating a synchronous pulse. If the current count value does not correspond to the sample count value, then the method performs a step of determining whether a signal level of said difference signal has changed, and if the signal level of the difference signal has changed then performing a step of ignoring further changes in the signal level of the difference signal until the current count value of the counter corresponds to the sample count value at which time the step of generating the synchronous pulse is repeated.

Disclosed is a spectrophotometry for a spectral transmission measurement of an extremely small volume of sample solution. A sampler 15 is formed of a flat plate member formed with a sample-holding hole 152 which penetrates the flat plate member in its thickness direction and has a reverse truncated cone shape, and a target sample solution is dropped into the sample-holding hole 152 of the sampler 15 positioned approximately horizontally and held in the hole 152 based on a surface tension of the sample solution in the form of a droplet S. Then, a measurement light is emitted to the held droplet S from directly above. A transmitted light getting out of the droplet S downward is introduced to a diffraction grating 19 through a window plate 17 and a slit 18, and dispersed in a wavelength dependent manner. The resulting light with dispersed wavelength components is detected by a multichannel detector 20 approximately simultaneously.

The improved AES processing method provides an efficient alternative to both Mips intensive multiplication and to conventional table lookup, used to multiply terms over a Galois field (GF). The improved method takes advantage of the fact that in the GF, any non zero element X can be represented by a power of a primitive element P. The improved method thereby results in a 2 by 256 table. The log base P of the terms being multiplied are looked up and summed, and the anti-log of the sum is looked up in the same table.
