Abstract: The present disclosure relates to systems and methods for guiding emergency personnel to a location in a facility proximate to an alarm that has been generated. In one aspect, a method may include detecting an alarm condition at a facility protected by a security system and determining a location at the facility of the alarm condition. The method may further include causing at least one indicator at the facility, which is proximate to the determined location of the alarm condition, to generate an identifying alert that is humanly perceivable from an exterior of the facility such that emergency personnel can identify the facility based at least in part on the identifying alert. In some aspects, the method may also include notifying a security representative of the alarm condition, and receiving a notification from the security representative indicating that emergency personnel are dispatched to the facility.

Abstract: A method and system for automatically identifying the type of communication interface used to couple a portable computer system with a second computer system, and for selecting the form of an application that is used with the type of interface. For example, a debugger application is collaboratively executed on the computer systems over the interface. When entering the debugger mode, software executed on the portable computer system identifies the type of interface by reading a resistance value of a pin. After determining the type of interface, the form of the debugger used with the interface is automatically selected. A similar process is followed for other applications that depend on the type of interface. The user does not have to manually identify the type of interface. Instead, in response to a command that is independent of the type of interface, the proper form of the application is automatically selected.

Abstract: A system and method for preventing unauthorized use of a device (e.g., a portable computer system) and for recovering the device when, for example, the device has been lost or stolen and an attempt to use it is made by someone other than an authorized user. The authorized user registers the device in a database at a central site (e.g., a Web site) using a unique identifier such as the device's serial number. If the device is lost or stolen, this information is entered into the Web site database by the authorized user. When the device is connected to the Internet using either a wireless or a landline connection, the device automatically communicates its unique identity to the Web site. The Web site performs a lookup and, if the database indicates that the device is lost or stolen, the device is so notified. In response, the device disables normal operation and instead will display, for example, the name and address of the authorized user.

Abstract: An electrical apparatus has an aperture block either retractably mounted or detachably mounted thereto. The aperture block has an aperture extending therethrough. The first end of a contact wire is disposed within the aperture while the opposed second end of the contact wire is coupled to the internal circuitry of the electrical apparatus. The aperture has a configuration complementary to the transverse cross section of a physical/electrical media plug. The media plug includes a contact block having a slot formed in the end that leads to a metal contact. As the media plug is inserted into the aperture, the first end of the contract wire is biased against the metal contact forming electrical connection between the media plug and the electrical apparatus. The aperture is also configured with grooves that releasably capture a flexible retention clip mounted on the pin block, thereby enabling mechanical engagement between the media plug and the aperture block.
