摘要:
A cover for one or more garbage bags comprising a bag made of material selected for its ability to deter pests including crows and seagulls. The bag has an open end that is provided with a drawstring, the drawstring being provided with a tightening device to permit a person to tighten the drawstring around the lower part of the garbage bags. The tightening device releases the drawstring as the bag is lifted from the garbage bag.
摘要:
A wireless communication device includes an antenna for wireless communication with a remote interrogator. Several embodiments are disclosed to increase the options available to designers of wireless communication devices. In some embodiments, the antenna is a quarter wavelength long with one end of the antenna being grounded to provide desired impedance matching characteristics. The position of the ground plane relative to the antenna is also varied between embodiments. The connection from a wireless communication chip to the antenna is also varied between embodiments to provide alternate structures.

Metallurgical powder compositions of the present invention include an iron based powder combined with a master alloy powder, as a mechanical property enhancing powder. The addition of master alloy powders has been found to enhance the mechanical properties of the final, sintered, compacted parts made from metallurgical powder compositions, especially at low sintering temperatures. Metallurgical powder compositions include at least about 80 weight percent of an iron-based metallurgical powder and from about 0.10 to about 20 weight percent of a master alloy powder. Master alloy powders include iron and from about 1.0 to about 40 weight percent chromium, and from about 1.0 to about 35 weight percent silicon, based on the weight of the master alloy powder.
摘要:
Apparatus for installation on a motorcycle which is capable of shielding one or more riders thereof from heat generated during motor operation. In preferred embodiments, apparatus with a plurality of detachable shield panels which are capable of protecting one or more riders from excess heat generated by the operation of a motorcycle, and, conversely, in which the shield panels can be removed to provide beneficial heat to the rider and/or passenger when desired.
摘要:
A method for manufacturing wireless communication devices for use in tracking or identifying other items comprises a number of cutting techniques that allow the size of the antenna for the wireless communication device. Further, the chip for the wireless communication device is nested so as to be flush with the surface of the substrate of the wireless communication device. Rollers cut the tabs that form the antenna elements. In a first embodiment, a plurality of rollers are used, each of effecting a different cut whose position may be phased so as to shorten or lengthen the antenna element. In a second embodiment, the rollers are independently positionable to shorten or lengthen the antenna element.

摘要:
An intelligent tracking system designed to accurately detect and track goods and/or materials present within a pallet. An identification reader is coupled to the pallet and used to detect identification devices, such as RFIDs, that are attached to the goods or materials contained therein. The pallet is constructed in a manner to allow and limit the identification reader to detect the identification devices that are contained only within the attached pallet. Thus, identification devices are automatically detected by the identification reader and information relating to the identification devices is stored in a database in order to track the contents of a specified pallet. In this manner, goods and/or materials can be continuously and accurately tracked for shipping or storing purposes in order to provide real-time tracking capabilities.
摘要:
A wireless communication device coupled to a wave antenna that provides greater increased durability and impedance matching. The wave antenna is a conductor that is bent in alternating sections to form peaks and valleys. The wireless communication device is coupled to the wave antenna to provide wireless communication with other communication devices, such as an interrogation reader. The wireless communication device and wave antenna may be placed on objects, goods, or other articles of manufacture that are subject to forces such that the wave antenna may be stretched or compressed during the manufacture and/or use of such object, good or article of manufacture. The wave antenna, because of its bent structure, is capable of stretching and compressing more easily than other structures, reducing the wireless communication device's susceptibility to damage or breaks that might render the wireless communication device coupled to the wave antenna unable to properly communicate information wirelessly.
摘要:
The invention relates to a RFID chip that is contained inside a rubber tire to provide wireless communication of information concerning the tire. For instance, it may be desirable to communicate pressure and temperature information concerning a tire during its manufacture and/or usage. The RFID chip is attached to the inside of the rubber tire and is capacitvely coupled to a conductive belt contained inside the tire to provide an antenna for radio-frequency communications and reception.
