Title: Single-carrier receiver having a channel equalizer interacting with a trellis decoder and a channel equalization method therefor
Inventor: KWON YONG-SIK
IPC: H04N7/015
Filed: 2003-11-04
Granted: 2009-04-14
Abstract: A channel equalizer for a single-carrier receiver interacting with a Trellis decoder and a channel equalization method therefor. The channel equalizer includes a first equalizer having a first feed forward (FF) unit for eliminating a pre-ghost of an input signal and a first feedback (FB) unit for eliminating a post-ghost of the input signal, a Trellis decoder for Trellis-decoding an output signal of the first equalizer, and a second equalizer having a second FF unit for eliminating the pre-ghost of the input signal and a second FB unit for eliminating the post-ghost of the input signal based on a signal decoded by the Trellis decoder. The first and second equalizers, interacting with the Trellis decoder, enable the equalization performance and speed of the channel equalizer to be enhanced.

Title: Flow control systems
Inventor: NEYER DAVID W
IPC: G05D7/06
Filed: 2002-06-13
Granted: 2011-08-23
Abstract: A flow controller which uses a combination of hydrostatic pressure and electroosmotic flow to control the flow of a fluid. A driving fluid (1204) whose flow rate is dependent on both hydrostatic pressures and electroosmotic flow can be used (a) directly as a working fluid in an operable device, for example a chromatograph, or (b) to displace a working fluid (1203) from a storage container (625) into an operable device (1301), or both (a) and (b). The driving fluid (1204) can be composed of one or more fluids. Part or all the driving fluid (1204) is passed through an electroosmotic device (100) so as to increase or decrease the flow rate induced by hydrostatic pressure.

Title: Conveying apparatus with piezoelectric driver
Inventor: CABLE JEFFERY L
IPC: B65G27/24
Filed: 2003-12-18
Granted: 2008-04-22
Abstract: A conveying apparatus comprises an elongated conveying bed which includes a proximal end and a distal end. A support structure for the conveying bed accommodates vibratory motion of a portion of the conveying bed extending from the proximal end a substantial distance toward the distal end but dampens vibratory motion at the distal end. In addition, a piezoelectric driver is operatively connected to the conveying bed adjacent the proximal end. Consequently, operation of the piezoelectric driver will induce a wave motion in the conveying bed which will effectively convey a material from the proximal end to the distal end.

The PIC includes a digital certificate personal to an authorized user and is operable to automatically install the certificate on the laptop computer once presented into the computer and once the user enters a valid password respective to the PIC. At this point, the laptop presents the certificate to a server via a network, and the certificate is checked for validity. If valid, the user is then permitted to log into the server. Having logged into the server, the user can remain logged in even as the PIC is removed and presented to different computing devices that are also able to connect to the server via the network. Typically, the user is only able to access the server through the computing device to which the PIC is attached.  The user is automatically logged out of the server after a predefined period of inactivity or according to such other criteria as may be desired.
