Filed: 1995-04-05
Abstract: A synchronous detector (200) has first and second mixer circuits (206, 208) and a voltage-controlled oscillator (212). The voltage-controlled oscillator provides a local oscillator signal directly to the second mixer circuit and indirectly to the first mixer circuit through a phase transformer (210). The output of the first and second mixer circuits are combined in a combiner circuitry (220) to produce a jitter cancelled output signal. The jitter cancelled output signal is filtered in a loop filter (214) and applied to the voltage-controlled oscillator to control the frequency and phase of the local oscillator signal. The combiner circuitry includes a summer (222) and a jitter cancellation filter (228). The jitter cancellation filter is preferably a high pass filter matched to spectrum of the signal detected. The output of the first mixer circuit is passed through the high pass filter into one input of the summer while the output of the second mixer circuit is passed to the second input of the summer.  The output of the summer is passed to the loop filter.

Filed: 1997-08-06
Abstract: The present invention discloses a system and method for securing a computer. This system detects an event such as said number of key strokes or a mouse click. This systems reads for the presence or absence of an unprompted password prior to detecting the event. If the proper password is provided, the system is deactivated. If the appropriate password is not provided, a monitoring computer is notified of the unauthorized use of the protected computer. In notifying a monitoring computer, the system turns off the speaker of the modem so that the monitoring computer can be notified without alerting the unauthorized user. When the proper password is not provided, the system also notifies the monitoring computer so that the monitoring computer can check the unique identifying number of the protected computer. The location of that protected computer can then be traced. Therefore, if the protected computer is lost or stolen, the location can be communicated to an individual, such as the protected computer's owner, in a very short period of time to allow recovery of the protected computer. Additionally, the monitoring computer also notifies an individual, such as the computer's owner, of the unauthorized use of the protected computer. Also, the system, if the proper password is not provided, prevents the transmission of data via the modem.

Patent CA-2214881-A1 (CA)
Inventor: FULLER DOUGLAS D
IPC: B41C1/10
Filed: 1997-09-08
Abstract: A plate-imaging system and a plate-cylinder support structure are coupled in a manner that achieves precise spacing between a writing head and tree surface of a lithographic plate. The imaging unit is designed to permit the writing head undergo controlled advancement toward the plate cylinder, and includes a pair of rollers fixed with respect to the writing head and spaced so as to facilitate rolling contact with peripheral segments of the cylinder.      When the imaging unit is brought into contact with the structure containing the plate cylinder, the writing head is advanced toward the cylinder until the rollers make contact with the peripheral segments. The alignment between the rollers and the writing head is fixed such that rolling contact between the rollers and the peripheral cylinder segments ensures proper spacing between the writing head and a plate mounted to the plate cylinder. To ensure a constant tangential (linear) rotation velocity of the plate cylinder regardless of its diameter, the plate cylinder is driven with a fixed-diameter drive gear. In this way, the tangential velocity of the plate cylinder is constant and determined by the pitch diameter of the drive gear.

Patent CA-2216903-A1 (CA)
Title: Encapsulation of transmitter and receiver modules
Inventor: ERIKSEN PAUL
IPC: H01L31/0203
Filed: 1996-04-26
Abstract: An encapsulated optocomponent comprises an optocomponent assembly (14) having an optical interface at one side, which comprises guide pins (27) for positioning a connected optical component or optical connector. The assembly (14) is attached to the outermost portion (10) of a flexible tongue (9), which is an integral part of a dielectric carrier such as a polymer carrier (7). On or inside the carrier and the tongue (9) thereof electrical conductive paths are arranged which are connected to the optoassembly (14) and to electrical driver circuits in a driver circuit assembly (13), so that the carrier also has the function of a conventional lead frame. The entire device is moulded into an encapsulating plastic material (25). In the moulding operation the positioning of the optoassembly in an accurately determined position and the retainment thereof in this position is facilitated by the flexibility of the tongue (9), not being affected for example by the fact that an injected encapsulating material may possibly displace the significantly larger driver circuit assembly (13) and its attachment area (5) on the carrier (7). This construction can also allow that only the optoassembly is encapsulated, the driver circuit assembly being protected in some other way, so that the flexible tongue (9) is exposed. This design can facilitate the accurate positioning of the optocomponent assembly on a circuit board.
