Abstract:
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.

In one embodiment, an electronic device is provided in a shoe. In one embodiment, a wireless (or wired) earpiece is provided to provide audio information to the user. In one embodiment, the shoe-mounted device includes a display to show time, caller-id information, temperature, pulserate, etc.
Abstract:
A real-time monitoring system that monitors various aspects of the operation of a refrigerant-cycle system is described. In one embodiment, the system includes a processor that measures power provided to the refrigerant-cycle system and that gathers data from one or more sensors and uses the sensor data to calculate a figure of merit related to the efficiency of the system. In one embodiment, the sensors include one or more of the following sensors: a suction line temperature sensor, a suction line pressure sensor, a suction line flow sensor, a hot gas line temperature sensor, a hot gas line pressure sensor, a hot gas line flow sensor, a liquid line temperature sensor, a liquid line pressure sensor, a liquid line flow sensor. In one embodiment, the sensors include one or more of an evaporator air temperature input sensor, an evaporator air temperature output sensor, an evaporator air flow sensor, an evaporator air humidity sensor, and a differential pressure sensor. In one embodiment, the sensors include one or more of a condenser air temperature input sensor, a condenser air temperature output sensor, and a condenser air flow sensor, an evaporator air humidity sensor. In one embodiment, the sensors include one or more of an ambient air sensor and an ambient humidity sensor.
Abstract:
A virus-proof diskless computer with data interface for filtering data is provided as a robust virus-proof user computer system. The computer system is provided without a hard drive such that the computer must boot from a disk every time the computer starts. In this way, the operating system and computer files will not be corrupted by the user's use of the machine. A data filtering interface is also provided that allows only certain data file types to be transferred through the data interface port. This will help prevent unwanted file types and viruses from being transferred to or from the computer system.
Abstract:
A signal repeater for receiving and re-transmitting signals from environmental transducers and the like, and for mechanically and electrically cooperating with existing electrically powered fixtures. More particularly, the present invention includes a housing unit for mechanically and electrically coupling to the powered fixture, a transceiver unit, and a first power supply electrically connected to the transceiver circuit and housed by the housing unit. The repeater is adapted to maintain the functionality of the fixture.
Abstract:
An irrigation system comprises sprinkler heads with an electrically configurable spray pattern, moisture sensors, and a controller. Based upon input signals from the moisture sensors, the controller dynamically configures the spray pattern of the sprinkler head to allow more water to fall on areas that need to be watered and less water to fall on areas that do not require additional water. The irrigation system can additionally comprise fire sensors. Based upon input from the fire sensors, the controller activates the sprinklers.

Abstract:
An apparatus is disclosed for practicing a method of treating viruses in the nasal mucosa. Vapor is generated, heated and delivered to the nasal mucosa in intermittent bursts, timed to coincide with inhalation. Control circuits are provided to maintain the temperature of the vapor at the point of delivery at a level greater than that necessary to kill viruses in the nasal mucosa. Timing circuits can synchronize the vapor delivery with a breathing cycle with heated vapor being supplied during inhalation and blocked during exhalation. Other circuits terminate operation when liquid is insufficient or after a predetermined timed interval.
Abstract:
Systems and methods for monitoring conditions that affect the quality of food being served. Conditions such as temperature and elapsed time affect the quality of food and the safety of food consumers. Various embodiments of monitoring systems can be incorporated with different types of food containers. Sensors such as temperature probes can provide temperature information about the container and/or the food being served. The monitoring system can use such information in conjunction with elapsed time information in various ways. The monitored information can be displayed generally “real-time,” or it can be stored for subsequent analysis. The monitored information can also be used to trigger an alarm or similar indicator when a condition detrimental to food-serving is present. Various embodiments of the monitoring system having such features can be packaged in various embodiments, including a self-contained unit and an assembly of modular components linked by wire and/or wireless connections.
Abstract:
A low cost, robust, wireless sensor system that provides an extended period of operability without maintenance is described. The system includes one or more intelligent sensor units and a base unit that can communicate with a large number of sensors. When one or more of the sensors detects an anomalous condition (e.g., smoke, fire, water, etc.) the sensor communicates with the base unit and provides data regarding the anomalous condition. The base unit can contact a supervisor or other responsible person by a plurality of techniques, such as, telephone, pager, cellular telephone, Internet, etc. In one embodiment, one or more wireless repeaters are used between the sensors and the base unit to extend the range of the system and to allow the base unit to communicate with a larger number of sensors.
