    摘要: A battery protection and monitoring system includes a plurality of MAFET (Mechanically Actuated Field Effect Transistor) switches, wherein each MAFET switch among the MAFET switches is capable of switching from an open switch condition to a closed switch condition or vice versa, such that the plurality of MAFET switches are connectable to a battery. Such a system further includes one or more transistors associated with and which communicate electrically with at least one MAFET switch among the MAFET switches. A PPTC (Polymeric Positive Temperature Coefficient) device is also associated with the transistors and the MAFET switches, such that the PPTC device, the MAFET switches and the transistors operate in association with one another and the open switch condition or the closed switch condition of the plurality of MAFET switches to identify, monitor and thus prevent at least one dangerous condition associated with the battery.

    摘要: A wireless monitoring system and method. A distributed electrical circuit can be printed on a dielectric film for wrapping pallets or containers in a logistic chain, wherein the distributed electrical circuit (e.g., a Wheatstone Bridge) detects a rupture of the film through an electrical resistance change of one or more elements of the distributed electrical circuit. The electrical resistance change is indicative of a potential tampering event. An electronic module can be provided that conditions and processes a signal transmitted from the distributed electrical circuit and thereafter transmits the signal wirelessly via an antenna to a monitoring station. Additionally, a monitoring station can be implemented, which communicates with a network and the electronic module, and permits a user in real time to receive data concerning the potential tampering event.

    摘要: Apparatus, methods, and systems for bonding a cover wafer to a MEMS threshold sensors located on a silicon disc. The cover wafer is trenched to form a region when bonded to the silicon wafer that produces a gap over the contact bond pads of the MEMS threshold sensor. The method includes a series of cuts that remove part of the cover wafer over the trenches to permit additional cuts that may avoid the contact bond pads of the MEMS threshold sensor. In addition the glass frit provides for isolation of the sensor with a hermetic seal. The cavity between the MEMS threshold sensor and the cover wafer may be injected with a gas such as nitrogen to influence the properties of the MEMS threshold sensor. The MEMS threshold sensor may be utilized to sense a threshold for pressure, temperature or acceleration.

    摘要: An example sensor that includes a first Schottky diode, a second Schottky diode and an integrated circuit. The sensor further includes a voltage generator that generates a first voltage across the first Schottky diode and a second voltage across the second Schottky diode. When the first Schottky diode and the second Schottky diode are subjected to different strain, the integrated circuit measures the values of the currents flowing through the first Schottky diode and the second Schottky diode to determine the strain on an element where the first Schottky diode and the second Schottky diode are attached.
