Methods and apparatus for detecting body vital signs through the use of a Bioelectric Impedance Spectroscopy (BIS), either by (a) direct contact with the person (such as through one or more of their fingers) or (b) measurement of reflections from a field projected into the person's body. The techniques may be implemented using the projected capacitive touch array in a device such as the screen of a smartphone or tablet computer, or the touchpad of a laptop computer.

Vital sign monitoring via touchscreen using bioelectric impedance

An apparatus, system, and method directed to the charging of electronic devices, and in particular to the wireless charging of battery enabled devices using FM band signals.

FM scavenging for wireless charging

An improved remote keyless entry (RKE) system for a vehicle to provide enhanced capabilities to a user. The improved RKE system may utilize directional antennas in the vehicle and in the FOB. Directional antennas may utilize devices equipped with orientation-independent antennas to determine the location. The system can exist in many different customizable configurations, sometimes utilizing orientation-independent antennas embedded in the vehicle or the FOB. The devices, systems and methods described herein may be used for an RKE in personal or commercial vehicles.

We present several unique techniques for using touch sensor arrays to detect fingerprint information and authenticate a user.

Techniques for fingerprint detection and user authentication

An antenna array consists of multiple sub-arrays of planar, rectangular conductive patches disposed over a cavity to provide a volumetric antenna array. Each sub-array consist of multiple patch elements, arranged typically in a square or rectangular pattern. Multiple sub-arrays are further arranged along a one-dimensional row, to provide one or more unit cells. Adjacent sub-arrays in a row may be oriented at 45 degrees with respect to one another. The assembly provides a wide bandwidth, orientation dependent, directional antenna via volumetric radiating elements that can be conformal to exterior surface(s) of a vehicle such as a roof or trunk or roll bar of a passenger car.

Low profile antenna-conformal one dimensional

A human safe wireless charging system using a circularly polarized source antenna that can radiate in either a hemispherical pattern or directional cardiod-like patterns at a 40-50, 150, or 200 MHz frequencies to a receiving loop antenna which is coupled to a parasitic receive element.

Low frequency rectenna system for wireless charging

An antenna assembly operating in the AM/FM, 3G and 4G cellular, WiFi, Bluetooth, satellite and 5G bands. The assembly provides a wide bandwidth, orientation dependent, directional antenna via volumetric radiating elements that conformal to exterior surface(s) of a vehicle such as a passenger car. The volumetric antenna elements may be further controlled by embedded components and/or surrounded by controllable ground plane elements. In one application, the antenna may be used to detect a direction of approach by person to, for example, operate only certain door locks.

Low profile antenna&#x2014;conformal

An antenna array for use in a passenger vehicle. Four of the roof support pillars are used as antenna elements. Each of the four pillars is electrically connected or coupled to one end of a corresponding meanderline component. The other end of each meanderline is in turn coupled to a radio receiver, typically through a combining network.

A scanning optical device suitable for use as a camera or solar concentrator.

We present several unique techniques for using touch sensor arrays to detect fingerprints and authenticate a user.

A method for operating a two-dimensional touch array by providing virtual grid intersections. The techniques may be used to improve the array resolution. It may also be used to detect fingerprint ridge and valley detail even when the finger is not moving, and when the array node spacing is much greater than the ridge and valley spacing.

Creation of virtual intersection points on a touchscreen to permit static, non swiping fingerprint user authentication

Techniques for implementing series-fed antenna arrays with a variable dielectric waveguide. In one implementation, coupling elements with optional controlled phase shifters are placed adjacent each radiating element of the array. To avoid frequency sensitivity of the resulting array, one or more waveguides have a variable propagation constant. The variable waveguide may use certain materials exhibiting this phenomenon, or may have configurable gaps between layers. Plated-through holes and pins can control the gaps; and/or a 2-D circular or a rectangular travelling wave array of scattering elements can be used as well.
