Patent number: 9493158Abstract: A miniature autonomous vehicle for operation on the public roads is disclosed. The small size allows efficiency for small payloads, but produces a danger of being overlooked by other vehicles. The size of the vehicle is less than driver operated vehicles and may be restricted to less than 200 pounds. Sensors determine the vehicles speed and the presence of environmental vehicles and use a processor to calculate the need for additional visibility. A visibility structure and support structure with lights or markers is controlled by the processor. The markers are controlled in their operation or position by the processor on the basis of the sensor data. Extending or raising and retracting or lowering the structure affects the air resistance and stability of the vehicle. The structure can be raised when the vehicle stops or is in traffic and lowered at road speeds in light or absent traffic.Type: GrantFiled: December 14, 2015Date of Patent: November 15, 2016Inventor: Thomas Danaher Harvey

Patent number: 9209516Abstract: An NFC component includes a first interface that can be used in reader mode and is configured to be connected to an antenna via an impedance matching external circuit. A second interface can be used in card mode and in reader mode and is configured to be connected to the antenna and to the first interface via the impedance matching external circuit. An internal module includes a first detection circuit configured to deliver a first detection signal that represents the phase antenna matching quality when the impedance matching external circuit and the antenna are indeed connected between the first interface and the second interface. The internal module is further configured to deliver a check signal from at least the first detection signal.Type: GrantFiled: July 9, 2013Date of Patent: December 8, 2015Assignee: STMicroelectronics (Rousset) SASInventor: Alexandre Tramoni

Patent number: 9196968Abstract: An antenna device includes a first dielectric substrate made of a high dielectric coefficient material, a plurality of first contact pads fastened on a periphery of a top surface of the first dielectric substrate, a plurality of second dielectric substrates made of the high dielectric coefficient material, and a plurality of Yagi-Uda antennae respectively disposed on top surfaces of the second dielectric substrates. The second dielectric substrates are fastened on the first dielectric substrate. Each of the Yagi-Uda antennae has a drive, and a plurality of directors disposed in an outside position of the drive and spaced from an outer side of the drive. The directors are shorter than the drive, and the directors are arranged along a direction of being gradually away from the drive and gradually become shorter. An inner side of the drive defines a signal feed point.Type: GrantFiled: June 20, 2013Date of Patent: November 24, 2015Assignee: CHENG UEI PRECISION INDUSTRY CO., LTD.Inventors: Ching Hsiang Ko, Kai Shih, Jia Hung Su

Patent number: 9191072Abstract: An embodiment of a RF identification device is formed by a tag and by a reader. The tag is formed by a processing circuit and a first antenna, which has the function both of transmitting and of receiving data. The reader is formed by a control circuit and by a second antenna, which has the function both of transmitting and of receiving data. The processing circuit is formed by a resonance capacitor, a modulator, a rectifier circuit, a charge-pump circuit and a detection circuit. The antenna of the tag and the processing circuit are integrated in a single structure in completely monolithic form. The first antenna has terminals connected to the input of the rectifier circuit, the output of which is connected to the charge-pump circuit. The charge-pump circuit has an output connected to the detection circuit.Type: GrantFiled: March 8, 2012Date of Patent: November 17, 2015Assignee: STMICROELECTRONICS S.R.L.Inventors: Alessandro Finocchiaro, Giovanni Girlando, Giuseppe Palmisano, Giuseppe Ferla, Alberto Pagani

Patent number: 9177454Abstract: A hard cover product with a pair of cover boards attached to an outer liner in spaced-relation to define a spine, with a thin-film ink-circuit security device printed on a laydown area, and having an inner liner. The laydown area can be defined in the spine, and the inner liner or an inner body attached to the cover boards conceals the printed security device from casual observation of its presence. The laydown area can be defined on a surface of a sheet laminated to another sheet to define one of cover boards. The laminated sheets sandwich the printed security device without a surface indication of the presence of the ink-circuit printed security device therein. In another aspect, the thin-film ink-circuit security device printed on a surface of the cover board is concealingly covered by the inner or the outer liner.Type: GrantFiled: February 28, 2014Date of Patent: November 3, 2015Assignee: SmartGuard, LLCInventor: Dale Hunt Nichols, Sr.
