Abstract: A method of cutting for an electronic cutter includes receiving a signal that a sheet has been loaded and receiving a size of the sheet. The method also includes receiving data from a removable electronic memory device containing shape data.

Abstract: A blade housing for an electronic cutting apparatus includes an outer housing having a distal end, an inner housing coupled to the inner housing and longitudinally selectively adjustable relative thereto and a blade rotatably coupled to the inner housing with a sharpened distal end. Adjustment of the inner housing relative to the outer housing adjusts an amount of the blade that protrudes from the distal end of the inner housing.

Abstract: An apparatus in an electronic control system allows two or three wire operation. A power supply can supply power to the enclosed circuitry in both two and three wire installations. Two separate zero cross detectors are used such that timing information can be collected in both two and three wire installations. Both zero cross detectors are monitored and are used to automatically configure the electronic control. Over voltage circuitry senses an over voltage condition across a MOSFET which is in the off state and turns the MOSFET on so that it desirably will not reach the avalanche region. Over current circuitry senses when the current through the MOSFETs has exceeded a predetermined current threshold and then turns the MOSFETs off so they do not exceed the MOSFETs' safe operating area (SOA) curve. Latching circuitry is employed to keep the protection circuitry in effect even after a fault condition has cleared.

Abstract: An electronic paper cutting machine includes a housing to which a drive roller is coupled for moving a sheet to be cut in a first direction and a cutter assembly coupled to the housing and moveable in a second direction that is perpendicular to the first direction. A user interface is incorporated into the housing for allowing a user to select via the user interface at least one shape to be cut by the cutter assembly wherein controlled movement of the drive roller and the cutter assembly causes a shape to be cut in the sheet.

Abstract: A system obtains a file associated with at least one interaction that satisfies a requirement of the application. The file (containing at least one instruction) is associated with a graphical user interface allowing a user to define at least one interaction, as a use case. The system transmits at least a portion of the file to a processor for processing of the portion of the file. The processor is selected based on at least one instruction. The system transmits a result of the processing to an engine in communication with the processor. The system transmits the result from the engine to a view renderer for execution of at least one instruction (that is contained in the file associated with at least one interaction that satisfies the requirement of the application). The system receives a response at the view renderer, and transmits the response from the view renderer to the engine.

Abstract: A biosafety cabinet includes one or more air filters below the work surface and a system for holding, sealing, replacing and disposing the air filters through the work access opening of the biosafety cabinet. The air filters under the work surface of the biosafety cabinet capture particulates entering the cabinet from the exterior environment and the particulates within the cabinet's work chamber. Instead of a mechanical clamp, the perimeter of the air filters are sealed using a gasket and a tape, eliminating the accumulation of the contaminants around mechanical clamps. The air filters may be accessed through the work access opening of the biosafety cabinet, packaged for disposal and removed from the biosafety cabinet without being exposed to the exterior environment. A filter cover with an adhesive surface is used to cover and lift the used, contaminated air filter within the biosafety cabinet.

Abstract: A biosafety cabinet has an air bypass system. The air bypass system reduces air noise and static pressure in the biosafety cabinet, and continues a supply of air to the blower, when the view screen or door is fully closed by providing an alternate path for the air entering the cabinet. The air bypass system further includes an armrest provided on the door sill. The armrest may have perforations on the front and rear surfaces of the armrest to allow the air to travel under the armrest, through an air inlet. The air bypass system additionally blocks germicidal light generated inside the biosafety cabinet from escaping when the view screen or door is fully closed.

Abstract: A biosafety cabinet includes at least one cable port disposed in a wall of the cabinet that allows small tubing and/or cables to enter the cabinet through the walls. The cable port eliminates problems associated with running the tubing and/or cables through an open door at the front of the cabinet. The cable ports enable the user to fully close the view screen door, while maintaining the ability to connect various tubes and/or cables to devices in the interior work area of the cabinet. The biosafety cabinet further includes a double wall configuration with negative pressure air space between the two walls. Air and byproducts or contaminants attempting to escape from the cabinet into the room or enter the cabinet from the outside environment is captured in the negative pressure area between the walls and transported directly to an air filter.

Abstract: A lighting control device for controlling the light intensity level of at least one lamp is disclosed. The lighting control device includes an actuator and a controller operable to cause the light intensity level of the at least one lamp to fade at a first fade rate that is based on the initial light intensity level of the at least one lamp upon a determination that the actuator has been actuated, to fade to off at a second fade rate upon a determination that the actuator has been actuated for only a single transitory duration, to fade from the initial intensity level to a preset desired intensity level at a third fade rate upon a determination that the actuator has been actuated for two successive transitory durations, and to fade to off in a predefined fade rate sequence upon a determination that the actuator has been actuated for more than a transitory duration. The first fade rate is based on a predefined fade-off time.

Abstract: A lighting control device for controlling the light intensity level of at least one lamp is disclosed. The lighting control device includes an actuator and a controller, such as a microcontroller, for example. The controller is operable to cause the light intensity level of the lamp to fade at a first fade rate when the actuator is actuated. If the controller determines that the actuator has been actuated for at least a predefined hold time, the controller causes the light intensity level of the lamp to fade at a second fade rate for a predefined long fade time. After the long fade time elapses, the controller causes the light intensity level of the lamp to fade to off at a third fade. The first fade rate is based on a predefined fade-off time that represents a time allotted for fading the light intensity level of the lamp from its initial light intensity level to off.
