Title: Process and apparatus for downloading data from a server computer to a client computer
Inventor: IOFFE EDWARD
IPC: H04L69/40
Filed: 1998-02-24
Abstract: A download of a data file from a server computer (10) to a client computer (12) is monitored by the client computer. The download is restarted automatically if a failure occurs. A failure may be a timeout, a loss of a connection, data errors, or other errors that terminate the download. The download may be restarted by instructing the server computer to start reading from a specified offset corresponding to an amount of data that was received reliably by the client, so that data is not unnecessarily retransmitted. This process increases the likelihood that a download will complete successfully.  The client program (20), if specialized for performing downloads, may be stored at the server. In response to a request to download a file, the client program is downloaded first, with the location of the requested file stored within the program. The client program is then executed on the client computer to transfer the requested file.

Title: Traction device
Inventor: MORIN ROBERT M JR
IPC: B60B39/12
Filed: 1999-09-23
Abstract: A traction device for a wheeled vehicle arranged to be laid on the ground in engagement with a tread portion of a tire to provide a traction grip to the tire. The traction device includes a U-shaped frame and a pair of claws constructed at the ends of the U-shaped frame and arranged to engage into cavities between the tire treads by a lever action on the traction device. The traction device further includes a plurality of transverse braces extending between a pair of longitudinal bars of the U-shaped frame, each transverse brace having a pair of traction cleats extending downwardly to engage with the ground and to elevate the traction device from ground in some measure.   One of the transverse braces is positioned at a region near a forward end of the U-shaped frame so that the corresponding pair of traction cleats maintain the device in a level attitude, prevent a lever action from being created, and prevent the U-shaped frame from tilting or projecting upwardly which may cause injury or property damage as the vehicle passes over the forward end of the device.

IPC: G06F1/00
Filed: 1998-03-24
Abstract: A system for locating and monitoring electronic devices utilizing a security system that is secretly and transparently embedded within the software, firmware, or hardware of a computer. This security system initiates the client computer to periodically and conditionally call a host system to provide unique identifying indicia and location information. In one embodiment. the security system calls the host through a public switched telephone network (PSTN) and transmits the indicia in encoded form. In an alternative embodiment, which may be incorporated concurrently with the PSTN application, the security system calls the host system through the Internet and provides the host with indicia encoded within the DNS query sent. The host system is able to identify the calling computer from the indicia and is able to physically locate the computer through either caller identification or by referencing the Internet links which were used to connect the calling computer with the host system.

Patent CA-2290239-A1 (CA)
Inventor: DOBLAR DREW G
IPC: H04L25/38
Filed: 1999-11-23
Abstract: A digital communication system is presented implementing a data transmission method which allows each of a pair of communication devices coupled to a transmission line to both transmit and receive data during each cycle of a clock signal (i.e., simultaneous bidirectional data transmission). The digital communication system includes a first and second communication devices coupled to opposite ends of a transmission line. Both the first and second communication devices operate in response to a periodic clock signal. The first and second communication devices simultaneously: (i) drive an output data signal upon the transmission line during a first portion of a period of the clock signal, and (ii) receive an input signal from the transmission line during a remainder of the period of the clock signal. The communication devices may be coupled to receive the clock signal via a clock signal line, or may include circuitry to generate and synchronize two separate clock signals. One embodiment of an input/output driver circuit is described, along with timing requirements which must be observed in order to achieve simultaneous bidirectional data transmission.

IPC: G01J3/50
Filed: 1998-10-30
Abstract: A modulated light source illuminates a target surface which possesses a certain color and shade of color. Light that is reflected from the target surface is detected by an optical detector. The output is compensated for any shift caused by ambient light, temperature of other external factors and demodulated to produce a substantially steady DC voltage that is indicative of the color or shade of color at the target surface. The steady DC voltage is converted using a look-up table or mathematical formula into a corresponding quantity or quality measurement such as analyte concentration, compensation being made for any variations in modulated light source intensity due to temperature change.
