Filed:

Dec 23, 1999

Appl. No.:

09/471544

Inventors:

Mark E. Howarth - Orem UT
David A. Jensen - American Fork UT

Assignee:

Landesk Holdings, Inc. - Salt Lake City UT

International Classification:

G06F 1300

US Classification:

710 33, 710 65, 710 67, 709203, 709208, 709217

Abstract:

Disclosed herein are a system and method for using a remote terminal to control processes executing on a client terminal by transmitting data to the client terminal emulating keystroke inputs at the client terminal. A remote control application program executing at the remote terminal initiates the transmission of a message for emulating keystroke inputs to the client terminal. The remote terminal also executes an operating system having logic for responding to a detection of any one combination of keystrokes of a set of predetermined combinations of keystrokes, independently of any application program executing on the remote terminal. While the remote control application is active, the remote terminal inhibits the operating system from responding to detected keystrokes and transmits a message to the client terminal emulating an input of the detected keystrokes at the client terminal.

Abstract:

Improved apparatus for unclogging a toilet. The apparatus includes a resilient sealing ring shaped generally to conform to the shape of the rim of a toilet, a support plate attached to said sealing ring configured such that a force exerted on the support plate is transmitted to the sealing ring to compress the sealing ring against the rim of the toilet forming a substantially airtight seal around the toilet bowl. The apparatus further includes a sealing device insertable into the toilet tank including a sealing surface configured to form a substantially air tight seal over the vent tube, said sealing device further including a member configured to mechanically block the operation of the valve such that air is substantially prevented from escaping from the bowl through the tank when the sealing ring is compressed.

International Classification:

G06F 1516

US Classification:

709246, 709248

Abstract:

The 16-bit process receives synchronized data from a hooked data function. As memory becomes available in a shared memory buffer, the 16-bit process writes the synchronized data to the buffer. The 16-bit process then signals the 32-bit process that synchronized data is ready to be transmitted over the network. The 32-bit process reads the synchronized data, stores it in a send buffer to free the shared memory buffer, then signals the 16-bit process that the shared memory buffer has been read. The 32-bit process then sends the synchronized data out over the network. In this way, a “thunk” that improperly releases the mutual exclusion semaphore is avoided. There can be more than one shared memory buffer, to allow the 16-bit process and the 32-bit process to read and write synchronized data to the shared memory buffers at the same time. The 16-bit process can use a callback function to ensure that data does not wait in the shared memory buffers for too long before it is ready by the 32-bit process and sent out over the network.

International Classification:

US Classification:

715788, 715778, 715800

Abstract:

A virtual display driver that can be dynamically loaded and unloaded for remote control of a host computing system. The host computing system includes an original display driver that updates an output display of the computing system based on display commands. A remote control executive executes in kernel-mode within an operating environment provided by the computing system and dynamically loads and unloads the virtual display driver as requested by a user. The remote control executive inserts hooks within the functions provided by the original display driver to trap the display commands received by the original display driver and direct the commands to the virtual display driver for communication to a remote client computer.

Abstract:

A system for monitoring modem use in a computer system is disclosed. The system includes a computing device and a computer-readable medium that is part of the computing device or in electronic communication with the computing device. The computer-readable medium includes instructions for the system to implement a method for monitoring the system for modem use. The method starts a background application on the system. A communication port is monitored for communication data. It is determined whether the communication data is a modem instruction. If the communication data is a modem instruction, a notification is prepared to be sent to an administrative system. The notification is sent to the administrative system. The notification includes identification information.

Abstract:

In an exemplary method, a filter driver on a computer system receives notification of an event during which a display screen on a display device of the computer system should be blank. An example of such an event is a remote management operation being performed on the computer system. The filter driver receives messages that are directed to a display driver for the display device. The filter driver receives the messages before they are received by the display driver. Some of the messages may comprise a power on message that, if received by the display driver, would cause the display screen to be powered on. The filter driver discards each power on message that is received during the event so that the display driver does not receive any power on messages during the event.
