Title: System for monitoring a roller cone drill bit
Inventor: SULLIVAN ERIC CHARLES
IPC: E21B10/08
Filed: 2001-10-26
Abstract: A roller cone drill bit 511 has at least one sensor 207 monitoring its behaviour during drilling. A monitoring circuit 529 housed in an electronics bay 530 in the shank 525 of the bit processes data from the sensor. Power may be supplied from a battery also located within the bit (figure 38A) and protected by a sealing cap. The monitoring circuit communicates with the surface via a mud pulse actuation system (figure 39) located between two mud flow ports (4083, 4085) in the bit and comprising a piston (4092) and cylinder (4094) connected to a signal nozzle (4088). The sensors may identify imminent seal failure by detecting changes in bit lubricant composition using an annular capacitor to measure the dielectric constant of the lubricant. Also disclosed is an erodible or dissolvable ball (1003, figure 32) that is released by the monitoring system to temporarily block the mud flow, sending a mud pressure pulse signal to the surface.

Title: Cyclical paging in a mobile communications system
Inventor: VAN LIESHOUT GERARDUS JOHANNES
IPC: H04W52/02
Filed: 2003-10-02
Abstract: The present invention relates to the field of paging in telecommunications. When the "wake up" paging channel is used for another service, e.g. Multimedia Broadcast Multicast Services (MBMS), then certain mobiles expecting a "wake up" page will be woken up unnecessarily, reducing battery life. It is likely that a small group of terminals will have regular paging cycles which coincide with the MBMS paging signals, and therefore receive a large number of unnecessary wake ups. This will considerably reduce the battery life of this group of terminals. The aim of the invention is for a large number of terminals to receive a small number of unnecessary wake ups, therefore spreading a smaller reduction in battery life over more users. Three methods are described; using different values of cycle length for regular and MBMS paging, MBMS paging having a variable cycle and a different paging indicator for the two pages.
