Title: Docking mechanism for notebook-tablet computer
Inventor: HOANG PAUL
IPC: G06F1/16
Filed: 2003-08-27
Abstract: A two-part docking mechanism that enables a tablet to dock onto a 'Laptop-Base Computer' and form a regular notebook. One part, a docking-cover, supports the tablet when the tablet pivots, assists the tablet to move 'in and out' of docking position and folds down to cover the keyboard when the tablet is not docked. The second part, an ejector plate, secures the tablet in the tablet's docked configuration and pushes out the tablet when the tablet is moved out of docking position. The docking mechanism design accommodates current laptop models and only requires modification to the lid of the laptop - the laptop inner components and all peripherals require no modification. If so desired, an optional tablet lock secures the tablet permanently to the docking-cover. The design also facilitates the conversion of most existing laptop designs into 'Notebook-Tablet' computers.

Patent CA-2444466-A1 (CA)
Inventor: RIPPOLONE JOSEPH D
IPC: F16L55/18
Filed: 2003-10-07
Abstract: A plumbing tool includes an elongated hollow shaft and a resilient member attached to the shaft adjacent a shaft end. The resilient member extends radially outward and is sized to closely fit within a pipe inner diameter. Once the pipe has been cut, the tool is forced into the pipe end and the resilient member closely fits within the pipe inner diameter to block fluid flow. As the shaft is hollow, fluid flow is diverted through the shaft. A valve is then passed over the tool to engage the pipe end. As the fluid is being diverted through the tool, the valve is then soldered to the pipe without concern for the heat sink effect of fluid passage through the pipe. Once the valve has been properly soldered to the pipe end, the tool is simply pulled through the valve and removed. Capping of the pipe end with the valve is therefore rapidly achieved with minimal disruption to the users.

Title: Pcr timing control in variable bit rate (vbr) transport streams
Inventor: THORSTEINSON THOMAS M
IPC: H04L12/56
Filed: 2004-07-28
Abstract: In a method for transmitting data in packets in a transport stream the temporal relationship is stored in memory with each of the packets in that a timestamp is attached to each packet that reflects the exact arrival time of a data element of the packet. To accomplish this, a firmware counter called the Receive Timing Register (RTR) is clocked by a local oscillator to generate a Receive Timing Register value at the time the PCR reference bit arrives to create a timestamp that is associated with each packet. The oscillator and firmware register are located on the card that receives the stream. Alternatively stuffing is applied to each packet to control the transmission rate by the length of the sequentially transmitted packets. This can be done at alternating faster and slower rates or can be applied between PCR packets.
