Patent CA-2342517-A1 (CA)
Inventor: KURJANOWICZ WLODEK
IPC: H01L27/108
Filed: 2001-03-30
Abstract: A planar 4T-2C DRAM memory cell which balances leakage to a first order to increase the data retention time is disclosed. The memory cell of the present invention uses MOS capacitors as load devices for a cross-coupled pair of pull-down transistors, instead of TFT transistors, pmos transistors or high resistive poly which have been used in similar circuits of the prior art. More specifically, the tunnelling current through the thin gate oxide of the MOS capacitors is used as the load for the cross-coupled devices. The cross-coupled transistors and the access transistors have thicker gate oxides in order to minimize their leakage. The resulting layout of the memory cell of the present invention has a 30 percent smaller area than the area of a conventional 6T SRAM memory cell. Data retention time in the memory cell of the present invention is about 10 times longer than previous 4T DRAM cells.

Title: Dryer control circuit
Inventor: ST LOUIS ROBERT MAURICE
IPC: D06F34/10
Filed: 2001-11-29
Abstract: A control circuit for a clothes dryer operating with a 120 volt power supply compensates for changes in the ambient temperature to compensate for premature advancement of the dryer timer motor during an automatic drying cycle. The control circuit has a thermally biased low outlet thermostat and a thermally biased high outlet thermostat which control the energization of a heater in the dryer. The low outlet thermostat and the high outlet thermostat each open circuit at respective lower and higher predetermined temperatures when the outlet air flow from the dryer drum reaches the lower or higher respective predetermined temperatures to thereby de-energize the heater and advance the timer motor. The control circuit includes a thermally biased ambient thermostat that is normally open and unbiased, and that switches control of the heater energization from the low output thermostat to the high outlet thermostat when thermally biased and when the ambient temperature rises above a predetermined ambient temperature. The ambient thermostat becomes thermally biased when the low output thermostat is open circuited. Both the low and high output thermostats are normally thermally biased during the automatic drying cycle and are un-biased during user time selected drying cycles so that the low and high temperature thermostats cycle on and off at higher temperatures than they would during the automatic drying cycle.

Patent CA-2374303-A1 (CA)
Inventor: FAVIER PASCAL
IPC: G08C15/00
Filed: 2002-03-04
Abstract: The present invention is directed toward providing a system for the remote monitoring and control of operating equipment. Through a series of sensors located on or near the equipment, a plurality of operating and production parameters are read and metered. Should any of the readings exceed predetermined levels, an alarm signal is triggered, thereby notifying service personal located remote from the equipment site. Through the automated resources at the monitoring site, the system automatically logs the readings, events, and alarms; communicates alarms to the appropriate personnel dependent upon the nature of the alarm, the type of equipment involved, and the location of the equipment.  Service and maintenance information and aids are available to personnel at the equipment site through a communication network to the remote monitoring site. Based on the alarm condition and equipment readings from the sensors, the system can automatically transmit commands to adjust the operating controls on the equipment to resolve the alarm condition.

Title: Optical fiber diffuser
Inventor: TAM ROBIN CHI-HUNG
IPC: G02B6/24
Filed: 2000-06-16
Abstract: Optical fiber diffusers for emitting light cylindrically along a length of the fiber diffuser (38) with preselected light intensity distributions along the length of the diffuser. The diffuser portion is defined by forming a distribution of scattering centers in a section of the optical fiber core (34) having a modulated index of refraction which acts to couple light radially out of the fiber along the diffuser section. The intensity distribution of light coupled out of the diffuser section of the fiber is controlled by controlling the profile of the modulated index of refraction, namely the coupling coefficient, along the length of the grating. Writing a grating into a multimode fiber provides a method of monitoring transmission in the fiber since some of the light can be coupled out and detected and interrogated. The diffuser devices can be used as sensors, since they also couple light incident on the diffuser into the core where it is transmitted to a detector.
