摘要:
An intelligent local irrigation system includes one or more sprinklers and a controller coupled to the one or more sprinklers via a wired or wireless connection and enabled to control the sprinklers thereby. A controller arrangement establishes connectivity with an internet service portal which stores a profile of the local irrigation system and which obtains information from internet-based resources. The internet service portal determines an irrigation schedule based on the profile and on information obtained from the internet-based information resources and provides the irrigation schedule to the controller arrangement for implementation.

An rate-of-rotation sensor having a Coriolis element, which is arranged over a surface of a substrate, is described. The Coriolis element is induced to oscillate in parallel to a first axis. In response to a Coriolis force, the Coriolis element is deflected in a second axis, which is perpendicular to the first axis. A proof element is provided to prove the deflection.
摘要:
A system for converting a voice input requested location to a destination location useable by a navigation device in a vehicle. The system includes a mobile communicator, preferably a mobile phone, in communication with a base station and a voice portal server. The voice portal server identifies through a voice recognition algorithm a destination location corresponding to a requested location verbally input by the vehicle occupant. The voice portal server may access the internet for additional information. The voice portal server may prompt the occupant to respond to interrogatories to narrow the possible matches for the requested location to one destination location. The destination location is transmitted from the voice portal server via the base station and via the mobile communicator to a decoder in an encoded format, preferably in DTMF (Dual Tone Multi-Frequency) format. The decoder decoding the destination location and transmitting the destination location to a navigation device. The navigation device plotting a selected route from the current location to the destination location. A method of using the system is provided. An in-vehicle apparatus using the system is also provided.

An integrated adjustable capacitor device and method for making such a device are provided. The adjustable capacitor includes an underlying electrode, a dielectric cavity, an upper electrode, and an etch cavity for removing sacrificial material from the dielectric cavity. The surface of the device is relatively flat due to epitaxal deposition of epi polysilicon and single crystal silicon. The adjustable capacitor system is capable of undergoing CMOS processes without requiring additional steps of covering the capacitor device to protect it and then removing the covering following the CMOS processes.
摘要:
A structural body which, at least region-wise, has at least one area which is in contact with a liquid or a gas flowing past, and which, at least to a great extent, is provided with a surface patterning made of a plurality of randomly or irregularly distributed geometric forms, in particular pyramids. At least one such structural body be used in a capacitive sensor with which, in particular, the dielectric constants or the conductance of a liquid or a gas can be determined.
摘要:
A gyroscope system including multiple rotating or oscillating disks filters out disturbance acceleration inputs such as vibrations or jarring while detecting and measuring external angular velocity. The gyroscope disks are decoupled from a substrate to decrease the impact of external vibrations on the gyroscope operation. The gyroscope disks are rotated in opposite directions or oscillated out of phase to decrease the impact of disturbance vibrations and jarring while more accurately measuring external angular velocities applied to the system.

A sensor node arrangement in a wireless network, includes a sensor to sense information, an RF transceiver to communicate the information to at least one element of the wireless network, and a coil to establish a secondary communications channel with a handheld device via inductive coupling, the secondary communications channel used, for example, to receive, during installation of the sensor node arrangement, a node identifier of the sensor node arrangement.
摘要:
A yaw-rate sensor including a first and a second Coriolis element that are arranged side-by-side above a surface of a substrate. The Coriolis elements are induced to oscillate parallel to a first axis Y. Due to a Coriolis force, the Coriolis elements are deflected in a second axis X which is perpendicular to the first axis Y. The oscillations of the first and second Coriolis elements occur in phase opposition to each other on paths which, without the effect of a Coriolis force, are two straight lines parallel to each other.
摘要:
A vibrating microdevice, such as a vibrating micromirror, includes a vibrating structure which is connected to a supporting body via at least one spring structure in an at least a largely floating manner, the spring structure including at least one torsion-spring element defining a torsion axis and permitting a torsional vibration about the torsion axis to be induced in the vibrating structure, the spring structure also including at least one converter structure, which at least partially converts forces acting at least largely perpendicularly to the torsion axis on the torsion spring element into forces acting at least partially parallelly to the torsion axis on the torsion-spring element.
