A ball and socket joint, including a pin located on either the socket or the ball and a groove located on the other of the socket or ball, the pin configured to engage the groove and translate along the length of the groove when the ball is located in the socket. An attachment surface for attaching a device to the ball and socket joint is also provided, and the pin and groove are arranged to prevent rotation of the ball about an axis that is parallel to the plane of the groove and extends through the attachment surface when the ball is located in the socket. A ball and socket joint includes a locking nut, the locking nut including a partly circular internal cross section and a second flat surface.

Ball and socket joint

A patch antenna comprises a radiating microstrip patch element; and a ground layer electromagnetically connected to the patch element, wherein the ground layer is configured such that a radiation pattern of the patch antenna comprises a beam perpendicular to the antenna aperture, and a sub-beam parallel to the antenna aperture.

Modified radar antenna array

A presence detection system () including: an RFID interrogator (); and a plurality of passive RFID tags (to MN), the RFID interrogator () is configured to: measure a received signal strength indicator (RSSI) level from each of the plurality of passive RFID tags (to MN); compare a measured RSSI level to a reference RSSI level for each of the plurality of passive RFID tags (to MN); and determine whether a difference between the measured RSSI level and the reference RSSI level is greater than a threshold value.

Presence detection using RFID tags and readers

A method of determining a position of an object, the method including: receiving a first signal reflected from the object using a first device, the first device a peer to peer wireless communication device, interrogating a native communication protocol on the first device to output a first angle of arrival corresponding to the angle of arrival of the first signal at the first device, using a second device remote from the first device to receive a second signal reflected from the object, the second device a peer to peer wireless communication device, interrogating a native communication protocol on the second device to output a second angle of arrival corresponding to the angle of arrival of the second signal at the second device, calculating the position of the object based on the first and second angles of arrival, wherein the first and second devices are isolated from each other.

Method and system for detecting an object

The present disclosure relates to detecting presence using a low-cost radar. A transmitted signal including repetitions of a transmitted signal is emitted from a transmitting antenna. A received signal including a combination of a plurality of reflections of the transmitted signal is received at receiving antennas. For each received signal, the received signal is processed to determine whether a threshold has been exceeded. When the received signal exceeds the threshold, presence due to a motion from a moving body is determined. When the received signal does not exceed the threshold, a periodicity of the received signal is measured to determine whether the periodicity of the received signal is within a vital range, and presence due to a vital sign is determined when the periodicity is within the vital range.

System and method to detect presence using low-cost radar

A method of using a radar sensor for a security system to determine a range for a sensed moving object or person, the method including: transmitting, from the radar sensor, a plurality of radar pulses and, when the object or person is present to reflect the radar pulses, receiving a corresponding plurality of pulses.
