Patent number: 9153113Abstract: A smoke alarm system specifically designed to detect smoke near a kitchen stove includes a transmitter assembly having a smoke detection device housed within an enclosure which hangs upon an oven door handle or other such appendage. The transmitter assembly further comprises a transmitter module that generates a wireless signal upon detection of smoke and transmits the signal to a remote receiver. When activated by the signal from the transmitter assembly, the receiver assembly produces sound and illumination type alarms, thereby warning occupants of smoke that is emanating from the stove, and the need to take immediate corrective action.Type: GrantFiled: December 18, 2013Date of Patent: October 6, 2015Inventor: Diane C. Jones

Patent number: 9134716Abstract: An aspirating smoke detector detects blockages and interruptions in a pipe system. Air is aspirated, by a ventilator and via the pipe system, from rooms and devices that are to be monitored, and monitoring takes place for any characteristics of burning. The air flow of at least one part of the aspirated air is measured, as is the air temperature. A blockage signal is emitted if the air flow falls below a predetermined lower limit value and/or an interruption signal is emitted if the air flow rises above a predetermined upper limit value. The rotational speed of the ventilator is increased as air temperature rises and reduced as air temperature lowers.Type: GrantFiled: July 11, 2011Date of Patent: September 15, 2015Assignee: SIEMENS SCHWEIZ AGInventors: Martin Terence Cole, Martin Fischer, Markus Loepfe

Patent number: 9127986Abstract: An apparatus and method for remotely monitoring the temperature of acrolein in a storage tank has a temperature sensor in communication with the acrolein in the tank and with a temperature transmitter. A global positioning receiver/transmitter communicates with the temperature transmitter and sends the temperature data to a remote base station via a linking satellite while also providing location data about the storage tank. At the base station, the temperature data related to the actual temperature of the acrolein in the tank is compared to predetermined temperature set points. These predetermined set points correlate to polymerization reaction of the acrolein. When the set points are reached, a response processor initiates a response to control the polymerization reaction of the acrolein in the storage tank.Type: GrantFiled: February 16, 2010Date of Patent: September 8, 2015Assignee: Multi-Chem Group, LLCInventor: Michael L. Harless

Patent number: 9123221Abstract: An electronic device may include a smoke detector. The electronic device may use the smoke detector to monitor for the presence of smoke. In response to detecting smoke with the smoke detector, the electronic device may issue an alert or take other suitable action. The electronic device may transmit alerts to nearby electronic devices and to remote electronic devices such as electronic devices at emergency services facilities. Alerts may contain maps and graphical representations of buildings in which smoke has been detected. Motion detectors and other sensors and circuitry may be used in determining whether electronic devices are being used by users and may be used in determining where the electronic devices are located. Alerts may contain information on the location of detected smoke and building occupants.Type: GrantFiled: May 20, 2013Date of Patent: September 1, 2015Assignee: Apple Inc.Inventor: Paul G. Puskarich

Patent number: 9088648Abstract: A system for effecting at least one prearranged notification after a calling instrument places a call using a predetermined number; the system including: (a) a jack unit for coupling the calling instrument with an outgoing telecommunication connection; and (b) a server unit coupled with the outgoing telecommunication connection. The server unit is coupled with a plurality of notification media. The jack unit detects when the calling instrument places the call using the predetermined number. When the call is completed, the jack unit alerts the server unit of a completion of the call to the predetermined number. The server unit responds to the alerting by effecting the at least one prearranged notification via at least one notification medium of the plurality of notification media.Type: GrantFiled: April 28, 2011Date of Patent: July 21, 2015Assignee: West CorporationInventor: Monica Ann Marics
