Abstract: Detecting traffic signaling of a mobile environment includes receiving image frames captured by an imaging device to detect a traffic signal candidate therefrom based on at least a vehicle location. A score having a predefined value is established for the traffic signal candidate. The traffic signal candidate is tracked by incrementing the score when the traffic signal candidate is determined to appear, based on a probabilistic estimator that indicates an expected value for a location of the traffic signal candidate, in a tracked image frame of the captured image frames. The score is decremented when the traffic signal candidate is determined not to appear, based on the probabilistic estimator, in the tracked image frame. The traffic signal candidate is recognized as a traffic signal based on whether the score is above a specified threshold.

Abstract: A linear-motion telescopic mechanism according to the present invention includes a plurality of block members (22) by which an arbitrary arm length is achieved in such a manner that the plurality of block member (22) are rigidly connected to each other so as to elongate a linear-motion telescopic joint (J3). On the other hand, by separating the plurality of block members (22) one by one from a rigid alignment of the plurality of block members (22), the linear-motion telescopic joint (J3) is contracted. The block members (22) unfixed from the rigid alignment are still serially connected but not in a rigid manner. That is, the block members (22) thus unfixed can be flexed in any directions, and therefore can be housed inside a support member (1) in a compact manner.

Abstract: Digital baseband channel signals are received and up-sampled to a common sampling rate. The digital baseband channel signals are filtered using low pass filters. Complex frequency shifting is performed of the filtered digital baseband channel signals based on the associated different channel frequencies to obtain digital channel signals, which are combined to generate a digital wideband multi-channel signal that is a digital representation of an analog wideband multi-channel signal that is based on combining analog channel signals that correspond to the analog baseband channel signals. A non-linear pre-distortion of the digital wideband multi-channel signal is performed, the non-linear pre-distortion adding at least one of a gain and a phase shift to the digital wideband multi-channel signal such that the digital channel signals included within the digital wideband multi-channel signal are compensated for a non-linear distortion effected on the analog wideband multi-channel signal by a high-power amplifier.

Abstract: The present invention discloses a drill rig relocation system. Lift frames are provided at opposite ends of a base box of a drill rig substructure. A lift cylinder and bearing mat assembly are rotatably connected beneath the lift frame. The bearing mat assemblies may be rotated to the desired direction for moving the drill rig.

The drill rig is supported on linear sleeve bearings slideably mounted in the bearing mat assemblies. Translation cylinders on the bearing mats expanded to move the rig by translating the linear sleeve bearings along the shafts. After the lift cylinder expands to place the bearing mat on the ground, the translation cylinders are retracted, providing the linear bearing with the full length of the shaft for the next movement.
