Title: Sensor based trackside train measuring system
Inventor: SIMON CHADWICK
IPC: G01B11/04
Filed: 2019-04-09
Abstract: A trackside train measuring system (1) for measuring a length (lM-N) of a passing train (100), includes two stationary sensors (11, 12) which are arranged along a train track (200) at a predetermined distance (d) from each other. Both sensors (11, 12) are connected to an analysis unit (13) which calculates the speed (s) of the train (100) by dividing the following values: s = d / (t2 – t1), wherein the time t1 is the time at which a predetermined feature (101, 102, 101’, 102’) of the train (100) passes a first sensor (11) and the time t2 is the time at which the same feature (100) passes the second sensor (12). The length (lM-N) of the passing train (100) is subsequently calculated based on the following equation: lM-N = s * (tM – tN), wherein the time tM is the time at which a predetermined feature (101, 101’) of the train (100) passes one of the two stationary sensors (11, 12) and the time tN is the time at which another predetermined feature (102, 102’) of the train (100) passes the 20 same of the two stationary sensors (11, 12). The sensors (11, 12) may be axle counters, and the total length of the train may be calculated by summing up several measured train portions. A measurement time window (possibly based upon train speed) may be used to set the time over which the length of a given train is sensed.

Title: Primitive fragment processing in the rasterization phase of a graphics processing system
Inventor: Robert Brigg
IPC: G06T15/40
Filed: 2019-06-19
Abstract: A rendering space is subdivided into a plurality of tiles, and primitive fragments are received (2102), each fragment corresponding to a pixel sample in a tile. A determination is made (2108) as to whether a depth buffer read is to be performed for hidden surface removal (HSR) processing of one or more of the fragments. The fragments are then sorted into a priority (2110) and a non-priority (2112) queue based on the depth buffer read determinations, e.g. by placing fragments for which a depth buffer read is not to be performed in the priority queue and placing fragments for which a depth buffer read is to be performed in the non-priority queue. Hidden surface removal processing is then performed on the fragments in the priority and non-priority queues wherein priority is given to the fragments in the priority queue. HSR may only be performed on fragments in the non-priority if the priority queue is empty, unless exception conditions exist, e.g. a full depth buffer cache. Using two queues to hold fragments between the coarse depth test logic and the HSR logic instead of one allows the latency associated with depth buffer memory reads to be masked more efficiently.
