Patent number: 10346655Abstract: Aspects of the present disclosure describe a battery-free touch sensing user interface (UI) for Internet of Things (IoT) and other smart spaces employing Radio Frequency Identification (RFID) readers and tags that we call RIO. With RIO, any surface may be a touch-aware surface by attaching RFID tag(s) thereto. RIO advantageously supports custom-designed RFID tags and therefore facilitates customized UIs to be easily deployed in a real-world environment. RIO employs impedance tracking that results from a human finger—or other appendage—touching a surface of an RFID tag, thereby changing a characteristic impedance of the RFID tag antenna. This change manifests as a change in the phase of the RFID backscattered signal and is advantageously used by RIO to track fine-grained touch movement over the RFID tag. Disclosed further are multi-tag environments in which RIO operates and demonstrations including continuous tracking of finger movement during a swipe to within 3 mm of its actual position.Type: GrantFiled: December 6, 2017Date of Patent: July 9, 2019Assignee: NEC CorporationInventors: Eugene Chai, Swadhin Pradhan, Sampath Rangarajan, Mohammad Khojastepour, Karthikeyan Sundaresan

Patent number: 7564342Abstract: An audio signal system for a vehicle remote locking mechanism provides an audio signal that is more intricate than a simple, sounding of the vehicle's horn or beep tone. Preferably, the audio signal may be varied among many possible sounds by the operator. More preferably, the system includes a digital audio source with a signal amplifier and loudspeaker. Most preferably, the digital audio source is programmable with recorded sounds that can be transferred from a remote bank of digital sounds, for example by being downloaded from an internet website.Type: GrantFiled: October 4, 2004Date of Patent: July 21, 2009Assignee: Ridetones, Inc.Inventor: David Erik Klein

Patent number: 7408446Abstract: There is provided in back of the instrument panel the motion sensor that transmits the radio wave continuously or periodically and receive the radio wave reflected in the vehicle compartment. Also, there is provided the burglar horn that executes specified alarming when a specified change in the reflected radio wave received by the motion sensor occurs. Herein, the motion sensor transmits the radio wave toward the instrument panel. Thereby, the stable burglar alarm operation can be performed.Type: GrantFiled: September 22, 2005Date of Patent: August 5, 2008Assignee: Mazda Motor CorporationInventors: Yoshifumi Umeo, Akihiro Furuzawa, Yasushi Hamada
