摘要:
A radio frequency identification (RFID) apparatus includes a housing, an RFID reader, and one or more RFID antennas disposed in the housing. The housing includes a first opening, a second opening, and a tunnel between the first and second openings. The housing is configured to be disposed over a track configured to transport a garment on hanger through the tunnel. The RFID antennas are configured to generate a first RFID signal substantially in the tunnel to interrogate an RFID tag associated with a garment on hanger as it transits through the tunnel. The RFID reader receives a second RFID signal transmitted by the RFID tag in response to receiving the first RFID signal. The RFID apparatus can include a segment of the track. The track can include a trolley configured to secure one or more garments on hangers. The trolley can include an RFID tag.

An RFID device includes an antenna defining a gap, with an RFID chip electrically coupled to the antenna across the gap. The RFID chip may be incorporated into an RFID strap, in which a pair of connection pads is connected to the RFID chip, with the connection pads connected to the antenna on opposite sides of the gap. Alternatively, the antenna may be connected to bond pads of the RFID chip. At least a portion of the antenna has a cross section with an at least partially curved perimeter. The cross section of the antenna may be differently shaped at different locations, such as having a flattened oval shape at one location and a substantially circular shape at another location. A portion of the cross section of the antenna may have a non-curved, relatively sharp edge, which may break through an outer oxide layer of a connection pad.

Ein Antennenbauelement (1) zur Verwendung in einem Empfänger eines passiven Zutritts-Berechtigungssystems und/odereines passiven Berechtigungssystem zum Starten eines Motors umfasst einen einstückigen magnetischen Kern (100) mit Gräben (113, 24, 131) zum Bewickeln mit elektrischen Leitern (10, 20, 30), diezueinanderorthogonalangeordnet sind, so dass ein Empfangdes Antennenbauelements (1) in allen Raumrichtungen gewährleistet ist. Der magnetische Kern (100) ist mit einem Injektionsverfahren hergestellt und enthält ein hochdichtes Material. Die elektrischen Leiter (10, 20, 30) weisen ein hochtemperaturstabiles Isolationsmaterial auf. Der bewickelte magnetische Kern (100) ist von einem Vergussmaterial (400) umgeben, so dass der magnetische Kern (100) und die elektrischen Leiter (10, 20, 30) vor mechanischem Stress geschützt sind.
摘要:
A wearable electronic patch with an enhanced radio antenna includes an antenna, radio circuitry, a base portion, a distal portion, and intermediate portion, and a spacer, configured to raise the antenna away from the base portion, and thus away from a wearer to improve radiation properties of the antenna. The spacer may be sized and shaped to expand from a compressed state, as it may be when the patch is packaged, to an expanded state that raises the antenna when it is applied to a wearer. Other aspects, embodiments, and features are also claimed and disclosed.
摘要:
The present invention relates to a transponder tag (10) that is operable by a mobile telephone, a mobile telephone for operating such a transponder tag (10), a method of operating the transponder tag (10), and a method for detecting the presence of a portable object. The transponder tag comprises a receiving unit (20) for receiving a wireless input signal. The transponder tag (10) is configured to obtain energy (EG) from the received input signal and to use the energy (EG) obtained from the input signal for transmitting by way of a wireless short-range connection a wireless output signal (SSR) that corresponds to a tag information (ITG) of the transponder tag (10). The receiving unit (20) is configured to receive a wireless input signal (STUP) at a frequency of at least one uplink band of a mobile telephone network. In this way, radiation energy of the mobile phone is used to achieve an energy-efficient and reliable operation of the transponder tag as long as the latter is located within a short distance of the mobile phone. This is useful for numerous applications. For example a person may use his/her mobile telephone to obtain a quick overview and/or a reliable confirmation that all his/her personnel belongings, e.g. keys or medical box, are "on board" at the moment the person leaves home.
