Abstract: A controller for a door system and an associated method of operation for actuating a door. The controller may be electrically coupled with a motor, an outer door switch and an inner door switch. The controller, activates a motor assist and may maintain a desirable current supply to the motor assist. Determining a relative position of the door and determining whether movement of the door is obstructed is performed. The controller actuates the door to an appropriate position and determines whether door operation exceeds a maximum time threshold. The controller may be configured to deactivate the motor assist once the door reaches an appropriate position or the door operation exceeds the maximum time threshold.

Abstract: A door assist system for use in a motor vehicle, to aid the user in opening doors by providing a power assist and operative controls. The door assist system can be retrofitted to existing vehicles such as armored motor vehicles used in military operations, to aid the user in opening heavy armored doors. The door assist system includes a programmable central controller coupled to internal and external open and close switches and sensors for activating door movement.

Abstract: A clip for securing one object relative to another, such as securing an object to a vehicle door or frame is provided. The clip is useful for installing a strip of safety sensors around the circumference of a vehicle door retrofitted with a motorized assist system.

Abstract: A system and method of installing sensors around a perimeter of a motorized armored vehicle door to detect obstructions between a closing door and a door frame are provided. A safety switch including a plurality of sensors formed of a sensing element molded in a casing is provided. Adjacent sensors are separated from one another by electrical connectors. A clip is used to retrofit the safety switch to the door.

Abstract: The present invention is a solid state relay having improved high speed turn on and lower heat dissipation of the power transistor. It uses a voltage level converter and AC-DC converter to provide a control input to an isolation transformer primary. The secondary of the isolation transformer is rectified and charges capacitors having capacitance much higher than that of control input of the power transistor. Transistors are coupled to a controller and the capacitors. The transistors are controlled by the controller to provide for the charging of the capacitors and later transferring of voltage from the capacitors into the capacitance of the control input of the power transistor so that it is charged quickly and turns on quickly. Similar operation occurs for quickly turning off the power transistor.

Abstract: A releasable document affixing assembly iremovably affixes a document sheet to a container or other object. The method allows for printing, affixing, and removal of the document sheet in few steps. The assembly generally includes two layers: the document sheet and a cover sheet. The document sheet has a first side and a second side that faces the container surface when the assembly is affixed to the container. The second side has a printable surface. The assembly positions the cover sheet as adhering a sticky side of the cover sheet to the first surface of the document sheet, which has a less-stick surface allowing for removal of the cover sheet from the document sheet. Prior to affixing, a border of the document sheet is removed to expose a border of the cover sheet sticky side to adhere the cover sheet to the container surface with the document sheet positioned therebetween.

Abstract: The current invention is a computer implemented method of evaluating relative efficiency of equipment by constructing a mathematical model of the operation of the equipment, calculating a distance between an actual operating point and the mathematically obtained optimal operating point of the equipment, and processing the distances to identify efficiency changes of the equipment.

Abstract: A system and method of surge limit control for turbo compressors including a turbo compressor having an inlet and an outlet, an anti-surge valve, a variable speed drive to operate the compressor, a rotational speed transmitter, an inlet temperature transmitter, an inlet pressure transmitter, an outlet pressure transmitter and/or guide vanes, and a controller, the controller including a PID control module wherein the computer uses information from the transmitters to continuously calculate a pressure ratio of the compressor at the compressor's current operational speed and compare it to the compressor's calculated pressure ratio at surge limit conditions. A computer generates a control signal for determining when to open the anti-surge valve if the pressure ratio of the compressor at the compressor's current operational speed guide vanes are within a user defined safety margin to the calculated pressure ratio at surge limit conditions.

Abstract: A method for controlling a system includes determining the lag in data from a variable signal. The data is arranged in matrices with one column for each variable signal. The columns are shifted to produce a plurality of different shifted matrices, each shifted matrix having a given value for the lag in data for each variable signal. A variable signal estimator processes each shifted matrix to output a variable signal function defining each variable signal in terms of its mathematical dependencies on all of the variable signals. A criterial function processes each variable signal function to provide an optimal lag value for each variable signal. A point calculation algorithm processes each shifted matrix to produce a point for each column. A lag estimator processes each point and optimal lag value to output a lag function defining each lag in terms of its mathematical dependency on all of the variable signals.

Abstract: A system and method that generate marketing intelligence by auditing the effectiveness of different segments of a cross platform marketing device. The system and method allow for coordinated media for marketing purposes. The coordinated media can include graphical displays, textual displays, and various pockets holding marketing materials with embedded smart tags or smart labels. The displays can cyclically change what products or offers are displayed. Each displayed product can be linked to one or more of the materials in specific pockets. In this manner, when a product or offer is shown and a predetermined number of marketing materials are taken from the specific pocket, marketing intelligence is generated as to the effectiveness of the display and the marketing materials based partially on the smart tags or labels. The marketing materials can be a coupon or voucher.

Abstract: A protective cover for an article such as a stethoscope, comprising a bag member of elongate form, closed at a first end and fully or partially open at a second, opposite end to form an enclosed volume for retention of the head and elongate connector body of a stethoscope. The two longitudinal sides of such bag member can be seamless; alternatively, such longitudinal sides can comprise two seam lines. The bag member is longitudinally, medially severable at an end portion that include the second, open end, to yield two free end segments for covering respective ear tubes of the stethoscope. The protective cover may further include retention means for positionally retaining the free end segments of the bag member in protective covering relationship to the ear tubes of the stethoscope, e.g., adhesive and/or compressive clips, or a transverse heat seal at marginal extremities of the free end segments.
