Title: Balloon help system
Inventor: GOLDSMITH DAVID B
IPC: G06F3/033
Filed: 1993-12-14
Abstract: A method, system and program for providing help information to assist in using an object oriented operating system. The help technique is also oriented to the particular area on the screen that is indicated by a portion of the help information.  When a user drags as object on a display screen and drops the object in close proximity with another object, a help display is presented with an indicator pointing to the associated area on the display. The help display provides information on the viability of the drop action and aids the user in navigating through the operation.  In a preferred embodiment, the help display is presented in a balloon display pointing to the objects upon which the operation is transpiring.

Patent CA-2140619-A1 (CA)
Inventor: CHARBONNEAU SYLVAIN
IPC: H01L21/18
Filed: 1994-12-12
Abstract: A method of selectively tuning the bandedge of a semiconductor heterostructure includes repeatedly forming a disordered region that is spatially separated from a quantum well active region and subsequently annealing the heterostructure each time after the disordered region is formed, so that vacancies/defects in the disordered region diffuse into the quantum well region and enhance interdiffusion at the well-barrier heterojunctions. Repeating, the disordering followed by annealing allows for a greater range in bandgap tuning. The heterostructures of interest are III-V material systems, such as AlGaAs/GaAs, where the active region includes structures such as a single quantum well, a multiple quantum well, or a superlattice.
Patent CA-2143425-A1 (CA)
Inventor: KULKARNI KRISHNAJI R
IPC: G01N35/08
Filed: 1993-08-27
Abstract: A continuous flow analysis system measures the cholesterol distribution among different lipoprotein classes in a blood sample. A blood plasma sample is separated into different lipoprotein classes by single vertical spin density gradient ultracentri-fugation. The sample is then introduced in a continuous succession into a continuous reagent stream which flows through a detec-tor. A signal of the reaction, such as the absorbance of the reaction product, is continuously monitored as the reaction mixture flows through the detector. The detector measures a transient signal thus allowing a relatively short reaction period. The absorb-ance data is digitized and analyzed with the help of a computer to generate a cholesterol profile indicative of the cholesterol con-centration in each lipoprotein class.

Title: System and methods for controlling rotary screw compressors
Inventor: CENTERS STEVEN D
IPC: G05B23/02
Filed: 1995-11-23
Abstract: An electronic control system dynamically varies the output capacity of a compressor by controlling plural valves associated with the compressor to provide pressurized air to a distribution system at an appropriate rate. The control system operates in any of three modes for standalone operation, including continuous run, auto/dual pressure band, and target pressure modes. In the first two modes, pressure bands are dynamically calculated based on load and unload values entered by an operator. These electronic control systems can also be connected in a peer-to-peer network to coordinate control of up to 16 compressors feeding the same distribution system, so as to maintain a desired target pressure in the system. A modem connected to the system supports remote diagnostics, monitoring, and control. Specialized startup, operating, and shutdown diagnostic algorithms prevent damage to the compressor and avert unsafe operating conditions.

Title: Battery charger and a process for automatic adjusting operation of a battery charger
Inventor: WYSS PATRICK
IPC: H01M10/44
Filed: 1996-09-17
Abstract: A process for automatically adjusting a battery charger according to characteristics of an accumulator battery being charged.  By measuring the charging voltage continuously, or at specific time intervals during the charging process, the assumed rated voltage of the battery being charged is determined.  By weighting the signal that is monitored through amplification or deamplification, the monitored signal is shifted into a signal range that is optional for monitoring. By repeated or continuous measurement of the charge voltage and determination of the weighting factor in accordance with the respective measurement result, an incorrectly estimated rated voltage at the beginning of the charging process may be corrected.  Consequently, a charging process is disclosed using a flexible system to determine the rated voltage of the battery being charged, thereby ensuring that the charging process is performed optimally in each case.
