Abstract: A touch sensor for detecting three-dimensional features of an object includes a rubber skin and a plurality of pins provided on one surface of the rubber skin. The rubber skin and pins are formed of materials having different colors to facilitate image processing. An image acquisition device is provided facing the one surface with the pins. When an object presses against the outer surface of the rubber skin, the rubber skin is depressed in a way that corresponds to the shape of the object. This spreads the pins, forming a pattern of a different brightness that is detected by the image acquisition device to thereby enable three-dimensional features of the object to be identified.

Granted: 2007-10-16
Abstract: A welding system (10) for real-time weld quality detection during resistance welding of a workpiece (26, 28) has a sensor assembly (66) including a winding (68) and a core (70) mounted generally coaxially within the cylinder (32) of the welding gun (30). A piston (34, 36) and piston rod (38) assembly are mounted for coaxial movement within the cylinder (32). The piston rod (38) has an end protruding from the cylinder (32) for affixing an electrode (16) thereto. Axial movement of the piston rod (38) relative to the cylinder (32) causes axial movement of the core (70) relative to the winding (68) to vary a length of core and winding overlap. The sensor assembly (66) produces an output signal based on the length of core and winding overlap to indicate piston rod position relative to the cylinder (32). Weld control logic (76) receiving the sensor assembly output controls welding of the workpiece (26, 28) in real-time.

Title: Data transmission over a communications link with variable transmission rates
Inventor: LUNDSJO JOHAN
IPC: H04J13/00
Filed: 1999-04-29
Granted: 2007-09-18
Abstract: An optimal data block size is determined for use in transmitting data at variable rates over a communications link in predetermined time intervals, where each predetermined time interval has the same time duration. Rather than varying data block size according to changes in transmission rates, which adds unnecessary complexity, the data blocks all have the same fixed size, i.e., the same number of data bits in each block. That fixed data block size is determined so that for all of the available data transmission rates, each predetermined time interval is fully occupied with useful information. The fixed data block size is determined based on a maximum frequency at which the transmission rate may change on the communications link and a lowest available transmission rate. Preferably, the fixed size of each date block is limited by predetermined maximum and minimum data block sizes in order to reduce the number of bit errors per data block, maintain a certain data throughput, and limit the amount of overhead bits relative to the number of payload bits for each data block.
