Patent number: 7411491Abstract: The invention relates to a device, in particular a patient monitoring system with a mobile terminal unit (1) for acquiring patient data. The measured data is transferred from the terminal unit (1) via a short-range radio technology (2) (e.g. Bluetooth) to a data monitor (3) arranged at the patient's bedside when the patient is in the vicinity thereof. If necessary, communication can be switched to a long-range radio technology (7) (e.g. WLAN) to ensure interruption-free data transmission while the patient moves around.Type: GrantFiled: May 27, 2004Date of Patent: August 12, 2008Assignee: Koninklijke Philips Electronics N.V.Inventors: Karin Klabunde, Guido Muesch

Patent number: 7411493Abstract: The invention provides a system and method for reporting hazard and event information from a mobile unit, and using that information to warn a user of an event or future hazard with reference to the mobile unit's location and/or intended direction of travel. Users may wirelessly report events or hazards to a central server in an event center by sending data to the event center via a wireless communications network. Secondary information may be included, based on the selected event type, along with images, audio, and video of the event. The event center stores event information, including event locations based on the locations of the transmitting mobile units, and makes this information available to allow other users to respond to the hazard or event.Type: GrantFiled: September 16, 2005Date of Patent: August 12, 2008Assignee: User-Centric IP, L.P.Inventor: Michael R. Smith

Patent number: 7411494Abstract: A low cost, robust, wireless sensor that provides an extended period of operability without maintenance is described. The wireless sensors are configured to communicate with a base unit or repeater. When the sensor unit detects an anomalous ambient condition (e.g., smoke, fire, water, etc.) the sensor communicates with the base unit and provides data regarding the anomalous condition. The sensor unit receives instructions to change operating parameters and/or control external devices.Type: GrantFiled: November 21, 2006Date of Patent: August 12, 2008Inventor: Lawrence Kates

Patent number: 7411496Abstract: Described is a cellular security system for monitoring an asset from a remote monitoring site without utilizing a signal modulating device or a cellular voice service. The cellular security system includes a detector, a display device, a cellular telephone that includes a camera and email capabilities, and a remote email device. When the detector detects an occurrence, the display device is activated such that the display device indicates the status of the detector. The cellular telephone captures a photo-image of the activated display device and composes an email and attaches the captured photo-image to the email. The cellular telephone sends the email to a remote email device, which is located at the remote monitoring site. From the remote monitoring site, the photo-image is viewed using the remote email device such that the status of the detector of the cellular security system is revealed.Type: GrantFiled: October 14, 2005Date of Patent: August 12, 2008Inventor: Jon B. Sharpe

Patent number: 7411497Abstract: Systems and methods for detecting presence and movement of intruders. Various embodiments of an intruder detection system can be based on, for example, a beam-interrupt detector or a thermal imaging device. The beam-interrupt detection based system can provide functionalities such as counting of intruders crossing a given beam. A plurality of such beams at different heights can also allow distinguishing different-sized intruders. The thermal imaging based detection system can provide functionalities such as tracking movement of intruders. A recording can be triggered by detection of intruder movement, thereby improving the efficiency of recording and reviewing information indicative of presence and movement of intruders in a monitored area. In one embodiment, non-intruders can be distinguished from intruders by querying an RFID tag carried by non-intruders. In one embodiment, non-intruders can be distinguished from intruders by facial recognition.Type: GrantFiled: August 15, 2006Date of Patent: August 12, 2008Inventor: Lawrence Kates
