Abstract: A cutting element may include a body, a concave cutting face formed at a first end of the body, the cutting face including one or more cutting ridges adjacent a cutting tip that are raised above the concavity of the cutting face and having a length that is at least about 10% of a diameter of the cutting face. An edge is formed around a perimeter of the cutting face, and the edge has an edge angle defined between a tangent of the cutting face and a cylindrical side surface of the body, the edge angle being acute at the cutting tip and varying around the perimeter of the cutting face.

Abstract: Fast network scanning is enabled by an accessory for a mobile phone. The accessory captures a wideband spectrum via a software defined radio that is independent of the mobile phone itself. The accessory consumes less than 3 W while verifying multiple base stations, of various standards, in an area. To achieve such a low power consumption, the accessory dynamically controls frequency, gain and bandwidth according to a prioritization of processing threads and a target scanning speed.

Abstract: Methods and systems for cellular device detection are presented. A signal processing receiver operable to determine a plurality of uplink parameters according to a downlink broadcast message. The signal processing receiver is also configurable to receive an uplink message according to the plurality of uplink parameters, thereby determining a presence and/or an identity of a cellular device by decoding the uplink message.

Abstract: A cutting element includes a substrate that is axially symmetric about a central axis. The substrate has a radius perpendicular to the central axis and that extends from the central axis to an outer surface of the substrate. A super-hard material is coupled to the substrate, and the central axis passes through the super-hard material. The super-hard material has an external surface defining at least one ridge protruding from a remainder of the external surface. A central point on the central axis is offset from the external surface of the super-hard material by a distance equal to the radius of the substrate. A distance measured from the external surface of the super-hard material to the central point is greatest at a position between 25° and 45° from the central axis of the substrate.

Abstract: Methods and systems for cellular device detection are presented. A wideband receiver is operable to acquire a block of digitized samples in an uplink frequency band. The wideband receiver is also operable to applying one or more computational kernels to the block of digitized samples, thereby determining a possible uplink transmission from the cellular device. The cellular device is confirmed when the bandwidth of the possible uplink transmission is verified and a cellular basestation, associated with the possible uplink transmission, is located.
