Title: Apparatus and method for magnetically controlling a hearing aid
Inventor: NEWTON JAMES R
IPC: H04R25/00
Filed: 1995-08-21
Abstract: An apparatus and method for controlling one or a plurality of adjustable operational parameters of a hearing aid by the movement of an external magnetic actuator into and out of proximity with the hearing aid.  The external actuator is handheld and comprises a magnetic source such as a permanent magnet. The hearing aid has a microphone for generating signals, hearing aid circuitry for processing the signals, an output transducer for transforming the processed signals to a user compatible form, and a magnetic switch, such as a reed switch, connected to the hearing aid circuitry. In one embodiment hearing aid circuitry has a plurality of adjustable operational parameters and includes control processing circuitry for switching between and controlling the adjustable operational parameters. The magnetic source is moved into and out of proximity with the hearing aid a selected number of times activating or switching "on" the magnetic switch each time. The control processing circuitry is configured to switch between the adjustable operational parameters on sequential activations of the magnetic switch for selection of an operational parameter to adjust. The control processing circuity is further configured to adjust the selected adjustable operational parameter after the activation of the magnetic switch is maintained a predetermined amount of times and to stop the adjustment when the magnetic switch is deactivated.

Title: System for sensing droplet formation time delay in a flow cytometer
Inventor: ESPOSITO RICHARD J
IPC: G01N15/10
Filed: 1995-10-13
Abstract: A droplet flow cytometer system which includes a system to optimize the droplet formation time delay based on conditions actually experienced includes an automatic droplet sample (75) which rapidly moves a plurality of containers (75) stepwise through the droplet stream while simultaneously adjusting the droplet time delay. Through the system sampling of an actual substance to be processed can be used to minimize the effect of the substances variations or the determination of which time delay is optimal. Analysis such as cell counting and the like may be conducted manually or automatically and input to a time delay adjustement which may then act with analysis equipement to revise the time delay estimate actually applied during processing. The automatic sample (73) can be controlled through a microprocessor and approriate programming to bracket an inital droplet formation time delay estimate. When maximization counts through volume, weight, or other types of analysis exists in the containers, the increment may then be reduced for a more accurate ultimate setting. This may be accomplished while actually processing the sample without interruption.
Patent CA-2204282-A1 (CA)
Inventor: SHANN PETER CHRISTIAN
IPC: F42D1/055
Filed: 1995-11-14
Abstract: This invention relates to a detonator firing circuit comprising a control unit and a plurality of detonator circuits. The detonator circuits are arranged to simultaneously receive a "fire" signal and the fire signal initiates all the delay arrangements to allow different groups of detonators to detonate at different times in accordance with a predetermined firing programme. In the present invention each detonator circuit has a code individual thereto and the control unit can control and transmit information to every detonator circuit, including the delay to be imparted to the detonator circuit. The identification code for each detonator circuit is preferably one of a large number of identification codes so that the likelihood of the two detonator circuits having the same identification code and being the same firing circuit is extremely small.

Patent CA-2227858-A1 (CA)
Title: Pressure-compensation system
Inventor: CORONADO MARTIN P
IPC: E21B33/12
Filed: 1998-01-27
Abstract: A downhole tool, such as a packer or bridge plug, employing an inflatable element, is disclosed. A pressure-compensation system is in fluid communication with the annular space between the body of the packer or plug and the inflatable element. The compensation system responds to thermally induced pressure load changes within the wellbore by allowing fluid to escape from beneath the inflated element when increases in fluid temperature in the wellbore increase the pressure under the element. The system additionally supplies fluid behind the element should the wellbore fluids decrease in temperature, thus lowering the pressure under the inflatable element.      The compensation system counteracts what would otherwise be a tendency for a pressure increase, which could subject the inflatable element to failure from overpressure and, conversely, supplies fluid to under the inflated element so that it can prevent unwanted loss of sealing or anchoring integrity of the packer or plug due to what would have otherwise been a pressure decrease behind the inflatable element.

Abstract: A container useful for keeping food or beverages warm or cold includes a combination lid and tray door assembly. The lid and tray are both coupled to thecontainer and to each other. The tray may be pivoted independently of the lid into a table top position and it may be separated from the container and used as a separate tray. The tray and lid are also pivotable together as an integral door assembly, and the lid is pivotable independently of the tray when the tray is removed or deployed as a table top. The overall height of the container is less than the overall length and the overall width so that the container has a low, stable center of gravity which permits it to be used on an unstable surface, such as an automobile seat, and so that the container does not obstruct movement or view of occupants of an automobile when it is used in an automobile. A handle of the container includes a holder for wrapping a power cord thereon, and, when disposed in a downward stowed position, provides a clearance between the bottom of the door and a supporting surface when the container is turned on its side to be used as a front opening cooler or warmer. The thermoelectric engine of the cooler/warmer is constructed as an integral cassette which can be installed or removed from the main body of the container in one piece. Finally, a finned heat sink used in the thermoelectric engine in conjunction with a centrifugal fan is formed as an oblique parallelogram to produce uniform air flow velocity across the width of the heat sink.
