Abstract: The present invention relates to radar systems and associated methods of operation. In one aspect, the present invention relates to an automotive radar system including at least one receiver configured to receive radar signals, a processing system configured to receive from at least one receiver, a received radar signal, process the received radar signal to generate a data frame that has dimensions of M rows by M columns of elements from a covariance matrix, determine a rank N of the data frame. The system is further configured to set all elements in a first subset of columns numbered N through M of the data frame to zero values to create a padded data frame, calculate a pseudo-inverse value of the padded data frame, determine a direction of arrival of at least one target using the pseudo-inverse value, and control an operation of a vehicle using the direction of arrival.

Abstract: A contact sensor and system for incorporation within clothing and other wearable items to monitor activity at a body surface. The sensor includes a contact membrane having a body surface contacting area and one or more base layers of knitted fabric. The base layer(s) is thicker over an area congruent with the body surface contacting area of the contact membrane. As a result, the contact membrane is urged into the forming of a raised outer surface for projection against a body surface.

Abstract: The present invention relates to deformable supports that provide a compressive force on a human or animal limb or body and can self-determine that force and monitor it. The invention further relates to garments comprising those supports and an associated system for self-determination, monitoring and communicating the compressive force.

Abstract: A measurement device comprising a curved container containing a liquid, a first indicator that is less dense than the liquid, and a second indicator that is more dense than the liquid, where the liquid substantially fills the container so that the position of the first indicator and/or second indicator in the container relative to the reference indicia may indicate an angle-related property of the device.

Abstract: The level of signal noise caused by fluid flow at a pressure transducer, such as a hydrophone or geophone, is determined by measuring the electric field induced when the fluid flow through a magnetic field. The electric field, which is proportional to flow rate, is measured by electrodes positioned about the transducer. The pressure due to the flow is derived from the flow rate voltage by a digital filter which may be adaptive, to allow for varying flow conditions, or which may employ a predetermined electric field/flow noise relation. This flow noise is then subtracted from the received signal, the resultant signal then being substantially noise free.
