Patent CA-2277097-A1 (CA)
Title: Buffered repeater with early filling of transmit buffer
Inventor: MENACHEM AVRAHAM
IPC: H04L12/56
Filed: 1998-01-05
Abstract: A repeater which introduces a minimum of delay in the transfer of a data packet from a source LAN to a destination LAN has an arbiter which grants access to a bus for a port to broadcast a received data packet onto the bus for loading the data packet into a transmit buffer for each outgoing port. The arbiter grants access only after all ports signal that their transmit buffers are ready to load the data packet from the bus. A transmit buffer signals that it is ready to be loaded at the passage of the collision window as it is transmitting a packet previously loaded into the transmit buffer. Accordingly, the transmit buffer is simultaneously transmitting the previously loaded packet and loading the new packet after the arbiter responds to the signal.

Title: F-sin (.theta.) lens system and method of use of same
Inventor: THIBAULT SIMON
IPC: G01J3/28
Filed: 1999-08-19
Abstract: An optical system for focusing an incident light so as to obtain a linear output (as a function of the wavelength, or of the order of diffraction, or of the grating spacial frequency or of the inverse of the index of refraction) comprises a diffraction grating and a lens, or a group of lenses, having a f-Sin(.theta.) characteristic,  where f is the effective focal length of the lens, or group of lenses, and .theta.  is an output angle of the light exiting from the diffraction grating. Therefore, a light incident on the diffraction grating reaches the lens, or the group of lenses, and results in a linear output.  Using the present invention in a spectrometer reduces the time consuming calibration process required and renders it easier because of the linear output between wavelength and pixels positions. The lens, or.group of lenses, has a diffractive, refractive or reflective property, or any combination thereof. The incident light can be a collimated, converging or diverging beam. The diffraction grating can be a plane, concave or convex grating.

Title: Force-feedback interface device for the hand
Inventor: YIM MARK H
IPC: A61B19/00
Filed: 1998-05-12
Abstract: A man-machine interface is disclosed which provides force information to sensing body parts. The interface is comprised of a force-generating device (106) that produces a force which is transmitted to a force-applying device (102) via force-transmitting means (104). The force-applying device applies the generated force to a sensing body part. A force sensor associated with the force-applying device and located in the force applicator (126) measures the actual force applied to the sensing body part, while angle sensors (136) measure the angles of relevant joint body parts. A force-control unit (108) uses the joint body part position information to determine a desired force value to be applied to the sensing body part. The force-control unit combines the joint body part position information with the force sensor information to calculate the force command which is sent to the force-generating device.

IPC: E05F15/603
Filed: 2000-04-26
Abstract: A closure operating device comprises a control unit for controlling a power actuator operatively connected to a closure to selectively open and close the same. The control unit and the power actuator are mounted to a casing adapted to be mounted on a wall. The casing defines an interior space which is normally closed by a lid which defines itself a compartment for receiving parts of the control unit. A limit switch mechanism is mounted in the compartment for automatically interrupting power transmission to the power actuator when the closure reaches a fully open position or a fully closed position thereof. The limit switch mechanism includes a pair of switch actuators threadably engaged on a shaft. The switch actuators are normally locked against rotation by an anti-rotation member. The anti-rotation member is adapted to be independently disengaged from the switch actuators to prevent accidental displacement of one of the switch actuators while the other one is being manually adjusted.
