An integrity verification subsystem can verify the integrity of software and firmware modules on a computing device at load time and/or at run time, independently of any operating systems that may be installed on the computing device. Some versions of the integrity verification subsystem can operate in physical and/or virtualized system environments, including virtualized mobile device architectures.

Operating system-independent integrity verification

A provisioning system can separately and independently provision different components for different purposes on a computing platform, and enforce component-specific purposes associated with the use of the individual provisioned components during operation of the platform. Some versions of the provisioning subsystem may operate on a virtualized mobile computing device and networked devices under control of the computing device. In some embodiments, the provisioning subsystem can enforce a desired 'purpose' of a provisioned component while simultaneously denying a corresponding 'anti-purpose.'

Componentized provisioning

A policy arbitration system manages the fundamental communications and isolation between executable components and shared system resources of a computing device, and controls the use of the shared resources by the executable components. Some versions of the policy arbitration system operate on a virtualized mobile computing device to dynamically compile and implement policy rules that are issued periodically by multiple different independent execution environments that are running on the computing device. Semi-dynamic policy changes allow for context enabled policy changes that enforce the desired system and component 'purpose' while simultaneously denying the 'anti-purpose'.

Flexible policy arbitration control suite

Polymorphic computing architectures can support and control separate, independently executable domains and other components on a computing platform. In some embodiments, the architectures may control the different domains and/or components according to different purposes. In some embodiments, the architectures can control domains and/or components to enforce a desired 'purpose' of a domain/component while simultaneously denying a corresponding 'anti-purpose'.

Polymorphic computing architectures

A domain manager system as disclosed herein can control the selective activation of multiple independently-operable execution environments or domains on a computing device in accordance with one or more policies. In some embodiments, activation of a domain may at least temporarily transform a general purpose computing device into a specific purpose computing device or 'appliance' by disabling use of one or more shared system resources by other domains.

Polymorphic virtual appliance rule set

An integrated indoor and outdoor positioning system and method. A first communication unit aperiodically emits an ultrasonic signal. A second communication unit receives the ultrasonic signal and transmits an identification signal in response to receiving the ultrasonic signal. One of the two communication units is placed at a predetermined position and the other of the two communication units is placed with an object. Identification information obtained from the identification signal is used to determine position information indicating that the object is at the predetermined position. The first communication unit is placed at the predetermined position and the second communication unit accompanies the object. Alternatively, the first communication unit accompanies the object and the second communication unit is placed at the predetermined position. One of the two communication units may also include a GPS receiver for receiving GPS signals from a plurality of satellites or pseudolites and computing position information therefrom. The GPS receiver applies differential GPS corrections computed by a GPS reference receiver to improve the accuracy of the position information. Position information is transmitted to a base station over an assigned radio frequency and during a time slot allocated to the communication unit that is transmitting the position information.

Portable integrated indoor and outdoor positioning system and method

Methods and apparatus for maintaining updated information on client/server object-oriented computing systems are disclosed. In accordance with one aspect of the present invention, a client/server object-based computing system includes a server which has a server object list that is arranged to include objects that are to be updated. The system also includes a client which has a client object list that contains an object in which the client has interest. The objects that are to be updated include the object in which the client has interest, and the server is arranged to send a message to the client that indicates that the object in which the client has interested should be updated on the client. In one embodiment, the client and the server are in communication over a low-bandwidth link.
