Patent CA-2017503-A1 (CA)
IPC: B60R16/04
Filed: 1990-05-24
Abstract: ABSTRACT OF THE DISCLOSURE    A vehicle preheating system which provides for the preheat-ing of the vehicle interior, as well as other components,  is disclosed.  The system includes an electrical heating element installed within the heater assembly of the vehicle and is sup-plied with electrical power by an external source.  The standard vehicle heater fan is supplied with electrical power from a transformer and rectifier in the circuit, thus using only exter-nal power rather than vehicle battery power.   The system is controlled by a timer controller,which may be preset to activate the heater assembly at some predetermined time prior to vehicle operation, and may provide for other component preheating devices such as engine and battery warmers.  The timer controller may activate each of these devices simultaneously, or independently at various times depending upon the lead time required to thor-oughly warm each component.  Alternatively, power may be applied to each device in turn in order to avoid excessive current draw from the external circuit.  The timer controller may also contain additional circuitry interconnected with the vehicle ignition system which provides a visual and/or aural warning when the ignition system is activated and the system is still plugged in and receiving power from the external source.  Alternatively, the timer controller may be set to deactivate the vehicle starter system when the timer controller is receiving external power.    The external power cord is contained on a reel which is installed within the vehicle body and is retracted onto the reel for stor-age when not in use.

Title: Apparatus and method for calibrating a printer to print data at a specified distance from the reference edge of a document
Inventor: BROOKS RALF
IPC: B41J29/46
Filed: 1990-06-01
Abstract: Abstract of The Disclosure A method for calibrating a printer to print data beginning at a specified distance from the reference edge of a document.  Several test documents are moved through a print station and a test symbol is printed on each of them with a preselected set of heating elements from a dot matrix thermal printer. The test documents are then processed through the same print station whereupon a sensor detects the reference edge of the document and the test symbol.  A master controller then determines a test symbol distance between the reference edge and the midpoint of the test symbol for each test document.  A plurality of test documents is processed in this manner, and the master controller determines an average test symbol distance for the plurality of test documents.  Using an average test symbol distance, the master controller determines the distance between the sensor and a given heating element of the thermal printer.  The master controller then calculates a calibration distance which is based on a comparison of actual distance between the reference edge and the preselected heating elements versus average test symbol distance.  In order to calibrate the printer to account for the calibration distance so that the printer prints data beginning at substantially the specified distance from the reference edge of the document, the master controller utilizes a stepping motor to make coarse calibration adjustments by advancing the document in full and/or half steps.  Fine calibration adjustments are made by selectively energizing heating elements of the thermal printer at the print station.  An apparatus is also provided which will print data starting at the specified distance from the reference edge of the document.
