Patent number: 10214026Abstract: A direct-to-object printer includes an object rotating subsystem. The object rotating subsystem includes an actuator with an output shaft, a holder mounted to the output shaft, the holder being configured to grip a portion of the object, and a controller operatively connected to the actuator. The controller is configured to operate the actuator to rotate the holder and the object gripped by the holder to enable at least one of the printheads in a printer to print a portion of a circumference of the object that is longer than a width of the at least one printhead.Type: GrantFiled: August 11, 2017Date of Patent: February 26, 2019Assignee: Xerox CorporationInventors: Timothy R. Jaskowiak, Chu-Heng Liu, Paul J. McConville, Jason M. LeFevre, Douglas K. Herrmann, Reid W. Gunnell

Patent number: 10208643Abstract: A particulate matter detection apparatus includes a particulate matter quantity detection means, a temperature detection means that detects the temperature of exhaust gas, a control unit and a heating means. The particulate matter quantity detection means includes a particulate matter deposition portion that deposits thereon part of particulate matter contained in the exhaust gas emitted from an internal combustion engine and a pair of opposite electrodes arranged apart from each other on the particulate matter deposition portion. The control unit determines a deposition quantity of the particulate matter on the particulate matter deposition portion based on an electrical signal outputted by the particulate matter quantity detection means and receives information on the temperature of the exhaust gas detected by the temperature detection means. The control unit controls the heating means to heat the particulate matter deposition portion to 300° C.-800° C. during a cold start of the internal combustion engine.Type: GrantFiled: June 12, 2015Date of Patent: February 19, 2019Assignee: DENSO CORPORATIONInventors: Go Miyagawa, Hirokatsu Imagawa, Masayuki Tamura

Patent number: 10180452Abstract: A test tool for a low voltage devices is described. The test tool comprises a voltage sensor, a current sensor, a diode sensor, a testing module, and an indicator. The voltage sensor determines a voltage between a first and second electrical wire from an alternating current (AC) transformer. The current sensor determines a current between the first and second electrical wires. The diode sensor determines a presence of a diode connected to the first and second electrical wires based on the current and the voltage. The testing module identifies one or more installation diagnostics related to a device to be coupled with the AC transformer. The indicator generates a visual or audible indicator corresponding to the one or more installation diagnostics.Type: GrantFiled: December 16, 2016Date of Patent: January 15, 2019Assignee: Nortek Security & Control LLCInventors: Ernesto Alonzo Marin, Angel De La Rosa
