Patent number: 7548171Abstract: A plurality of wireless sensors can be placed within a large system in various locations to monitor critical elements of that system. Each wireless sensor can include sensor elements usable to monitor one or more parameters of an element of the system and a wireless signal transmitter, such as, for example, a speaker or an antenna. Each sensor can transmit one or more unique identifying signals to a signal-receiving device, which can be processed by a signal processor. The signal processor can determine each received signal, the sensor corresponding to that identified signal, and the time the wireless signal was generated. Based on this information, the wireless signals can be diagnostically compared against expected values for the system being monitored and evaluated. If a discrepancy is detected, then the components and/or subsystems within the system that are implicated in the discrepant wireless signals can be evaluated for possible errors.Type: GrantFiled: December 19, 2002Date of Patent: June 16, 2009Assignee: Xerox CorporationInventors: Xenofon Koutsoukos, Patrick C.

Patent number: 6417915Abstract: In an image-forming system, an image-forming substrate is used, which has a sheet of paper, and a layer of microcapsules coated over the sheet of paper. The layer of microcapsules includes at least one type of microcapsules filled with an ink. A shell wall of each microcapsule is formed of resin, which exhibits a temperature/pressure characteristic such that each of the microcapsules is squashed under a predetermined pressure when being heated to a predetermined temperature, thereby discharging the dye out of the shell wall. A printer, having a roller platen and a thermal head, forms an image on the substrate. The platen locally exerts the pressure on the microcapsule layer. The thermal head selectively heats a localized area of the microcapsule layer, on which the pressure is exerted by the platen, to a temperature in accordance with an image-information data, such that the microcapsules in the microcapsule layer are selectively squashed and an image on the microcapsule layer.Type: GrantFiled: July 24, 1998Date of Patent: July 9, 2002Assignee: Asahi Kogaku Kogyo Kabushiki KaishaInventors: Minoru Suzuki, Hiroshi Orita, Hiroyuki Saito, Katsuyoshi Suzuki, Koichi Furusawa
