Abstract: An anti-theft device for protecting a portable electronic device from theft or unauthorized removal in a retail environment is provided. The anti-theft device includes a shroud configured to at least partially receive and engage a portable electronic device. The anti-theft device also includes a dock configured to releasably engage the shroud. The dock is configured to engage the shroud in a locked configuration so as to prevent removal of the shroud and the portable electronic device from the dock and to disengage the shroud in an unlocked configuration so as to allow the shroud and the portable electronic device to be removed from the dock.

Abstract: A method of remanufacturing a replaceable consumable unit includes providing the replaceable consumable unit including a first electronic circuit, with the first electronic circuit being at least partially inoperable; providing a second electronic circuit; communicatively connecting the second electronic circuit to the first electronic circuit; and intercepting, by the second electronic circuit, signals sent by an imaging system to the first electronic circuit.

Abstract: An electronic module for use in a printer consumable unit includes a first input and output (I/O) port adapted connected to an external contact, and a second I/O port connected to the external contact. Circuitry controls the electronic module and responds to read memory commands and write memory commands received through the external contact on the I/O ports. A memory stores data. A third port is connected to the external contact and adapted to source current. The circuitry is initially configured to send and receive data through the first I/O port. The circuitry tests the functionality of the first I/O port by directing the third port to source current and drive the external contact to a predetermined voltage, and read a voltage received by the first I/O port in response to sourced current. If the circuitry determines the first I/O port is not functioning correctly based on the read voltage, the circuitry will send and receive data through the second I/O port.

Abstract: In the toner cartridge recycling and remanufacturing industry, used xerographic products are reconditioned, repaired, and some are refilled with toner. Part of the refurbishment process is the replacing of used and worn components, including an electronic circuit, which has been spent. The electronic circuit is a critical component of the replaceable consumable unit and is used by the printer to store information used in the operation of the printer. Information stored in this electronic circuit relates to how much toner is remaining, the cartridge type, operating characteristics, and so forth. Some of these circuits have been designed for a one-time use application. For example, once the printer has determined that all of the usable toner has been consumed, the printer will essentially turn off the circuit in a replaceable consumable unit and the replaceable consumable unit will no longer function.

Abstract: A converter circuit for converting an alternating signal representing continuous rotary position into a further signal representing discrete rotary position samples the polarity of an envelope of the alternating signal and develops a state change in the further signal when the envelope changes polarity.
