A universal plug and play (UPnP) device makes itself known through a set of processes—discovery, description, control, eventing, and presentation. Following discovery of a UPnP device, an entity can learn more about the device and its capabilities by retrieving the device's description. The description includes vendor-specific manufacturer information like the model name and number, serial number, manufacturer name, URLs to vendor-specific Web sites, etc. The description also includes a list of any embedded devices or services, as well as URLs for control, eventing, and presentation. The description is written by a vendor, and is usually based on a device template produced by a UPnP forum working committee. The template is derived from a template language that is used to define elements to describe the device and any services supported by the device. The template language is written using an XML-based syntax that organizes and structures the elements.

Stationary and on-board battery chargers, methods of charging batteries, electric-vehicle chargers, and vehicles with chargers, including electric vehicles and hybrid electric vehicles. Chargers may automatically charge at the correct battery voltage for various types of batteries. Chargers have variable AC power supplies controlled by digital controllers, isolation transformers, and rectifiers. Transformers may be foil-type, and may have copper foil. Power supplies may be variable-frequency generators and the controllers may control the frequency. Electric vehicle chargers may have card readers, and vehicles may have batteries and a charger. Methods of charging include identifying the battery type and gradually increasing the charging at different rates of increase while monitoring charging voltage, charging current, or both, until a current lid is reached. Charging may occur at constant current and then at constant voltage.

A branding process provides a networked computing device with initial set up information, including a name, a public/private key pair, and a set of certificates the device will need to inter-operate with other devices in the trust group. A branding device conveys the initial set-up information to the networked computing device via a limited access network interface, or alternatively via a broadcast network media with the device enclosed in a wave guide and/or Faraday cage. The networked computing device can then use the set up information to verify that other devices on the network that seek to interact with the device are also members of the trust group, with which networked computing device can interact.

A push-to-release latching mechanism for retaining a transceiver module in a communication port of a computer or server is provided with a beam spring structure for positional restoration of the latch member, and the latch is supported and moveable relative to the host transceiver module. The latch member may be formed to include camming surfaces that facilitate the insertion of the transceiver module into a communication port and mate with a guide rail and connector resident in a communication port. The latch member may be adapted to latch with a rigid latch bar or a cantilevered spring. Additionally, the latch may be formed with a camming surface which insures that the latch is displaced to a latching position whenever network cables are connected to the transceiver module by camming the latch into the secure, latched position and subsequently preventing the latch from moving to an insecure or unlatched position. The latch member is pivotally supported on the transceiver module in a shaft/journal arrangement and thus is removed from the communication port whenever the transceiver module is removed, thereby preventing the latch from projecting from the communication port and being subject to damage. The latch member may be formed with a living hinge to provide a pivot axis and one end of the living hinge may be attached to a electronic module chassis or to a support structure which may be mated with a electronic module chassis for easy replaceability.

A method and apparatus for signalling the surface operator about downhole conditions. Sensors located downhole collect data while drilling and the data is processed to determine bit failure, for example. When the sensor data indicates a failure, the pressure of drilling mud is varied using a valve on the downhole unit, and this pressure variance is indicated by a pressure gauge visible to the operator. This pressure change tells the operator a failure has been indicated.

A reliable remote copy system is provided at low costs. The remote copy system includes a first storage system connected to a first upper level computing system to transmit or receive data to or from the first upper level computing system; a second storage system connected to the first storage system to receive data from the first storage system; and a third storage system connected to the second storage system to receive data from the second storage system and connected to a second upper level computing system to transmit or receive data to or from the second upper level computing system. Therefore, failover can be made from the first upper level computing system to the second upper level computing system. As a result, the upper level computing system connected to the second storage system is not required, and an inexpensive remote copy system can be realized.

A long throw Pop-Up Irrigation Nozzle assembly has no oscillating or rotating parts and includes a cylindrical body having a fluid inlet and a sidewall defining at least one fluidic circuit configured to generate a selected spray pattern when irrigation fluid flows through the body. In order to throw long distance, droplet velocity, droplet size and droplet initial aim angle determine the throw to provide a low precipitation rate (“PR”) for fluidic sprays. The nozzle assembly and method of the present invention achieve a PR of 1 in/hr or less and good spray distribution with a scheduling coefficient (“SC”) of about 1.5 without utilizing any moving components to provide a significantly more cost effective nozzle assembly, as compared to prior art rotator nozzles.

The present invention discloses an interlock attaching strap system, comprising a carrier having a plurality of first webbing strips transversely, evenly and spacedly affixed thereon, a holder having a plurality of second webbing strips transversely, evenly and spacedly affixed thereon, wherein by overlapping the carrier and holder, the first webbing strips and the second webbing strips are capable forming an elongate interlocking channel; at least an elongated interfering strap, which is longitudinally extended on the holder, having an affixing end extended from a peripheral edge of the holder and a free tab end, arranged to slidably pass through the interlocking channel and is hooked onto the last webbing strip so as to securely reinforce the holder on the carrier via the interfering strap.

A mobile electronic device with an image sensor and a shutter key. The shutter key includes a touch sensor and a resilient switch. A processor in the device is configured to activate an automatic camera function, such as an autofocus function when a user touches the touch sensor. The processor is also configured to photograph a subject when the user presses the shutter key and thereby activates the resilient switch.

A disposable microsensor is designed, fabricated and tested for standard BOD (Biochemical Oxygen Demand) measurements. A transparent Cyclic Olefin Copolymer (COC) substrate is used for sensor fabrication. Standard lithographic procedures in addition to techniques like screen printing and electroplating are used to fabricate the sensor. A microbial strain of Trichosporon Cutaneum is immobilized over one pair of sensor electrodes while the other is used as a reference. Depending on the respiratory activities of the microbial strain in different samples, the BOD values of the samples can be measured in terms of difference between the output signals. The sensor layer is attached to an injection-molded passive microfluidic channel on the top. Advantages of the BOD microsensor include, but are not limited to, fast BOD measurement, disposability because of its low cost, chemically inert polymer substrate, flow-through sample injection scheme and integration of on-chip optics.

A profiling bed or similar support surface having a back section, seat section, thigh and calf section convertible to a chair configuration. The back section is mounted on an angled slide to retract as it is rotated. The angle of the slide also provides upward lift of the back section as it is retracted and rotated. This combination of movements mimics the way a person's tissues stretch when they move to a sitting position, reducing pressure and shear. At the same time, the thigh section can be rotated to an incline and the calf section either raised into a horizontal configuration or lowered to a chair configuration during movement of the thigh section. In another embodiment the thigh section is also mounted on a slide to retract towards the foot end as it is rotated to an incline, providing reduction of abdominal strain and increased comfort.
