Title: Management protocol, method for verifying and transforming a downloaded programme fragment and corresponding systems
Inventor: LEROY XAVIER
IPC: G06F9/45
Filed: 2000-08-21
Abstract: A method and system for transforming and verifying downloaded programs fragments with data type restriction in an embedded system in which a program fragment being temporarily stored a verification process of the stored program fragment object code is executed instruction by instruction so as to discriminate for each instruction the existence of a target, a branching instruction target, a target of an exception handler call or a target of a subroutine call. On the occurrence of a target of a branching instruction as the current instruction, the empty status of the stack is verified and the program fragment is rejected otherwise. A verification process and updating of the effect of the current instruction on the data types of the type stack and the table of register types is performed. The verification process is successfully executed instruction by instruction until the table of register types is stable, with no modification being present, and interrupted with the program fragment being rejected otherwise.

Title: Improved wellbore pump
Inventor: LEE DAN
IPC: F04B47/12
Filed: 2002-04-19
Abstract: The wellbore pump of the present invention comprises a plunger having passage means which may be open or closed by a valve operated by a piston which is biased in the open position by a spring of selected strength such that the wellbore pressure may overcome the spring to close the valve when the accumulated hydrostatic pressure reaches a certain value. When the valve closes the reservoir pressure forces the plunger to the surface and causes the accumulated liquids to be pumped out of the wellbore. A stem extending from the top of the piston engages a top plate and causes the valve to open when the plunger reaches the top of the wellbore. Means is provided whereby the valve opens when it reaches the top of the wellbore and a latch may be provided to retain the plunger from returning to the bottom of the well.
