Abstract: Systems and method for providing a user with increased flexibility and control over the appearance and behavior of objects on a user interface. Sets of objects can be grouped into themes to provide a user with a distinct overall impression of the interface. Themes can be switched dynamically by switching pointers to drawing procedures or switching data being applied to these procedures. To buffer applications from the switchable nature of graphical user interfaces, colors and patterns used to implement the interface objects are abstracted from the interface by, for example, pattern look-up tables.

Abstract: A method for controlling a scheduler on a computer display including the steps of: a) dislaying a calendar in a calendar area on the computer display; b) choosing at least one date on the calendar; and c) displaying a schedule in a schedule area on the computer display for the chosen date or dates, where both the calendar and the schedule remain active and within a single window. In one embodiments, the method is implemented on a pen-based computer system, where a stylus can choose a desired date or dates on the calendar to automatically display the schedules for that date or dates.

Abstract: A power supply provides a voltage to a digital camera. If the power supply voltage falls below a predetermined threshold, a voltage sensor generates a signal to a power manager. In response, the power manager configures the camera into a lower power consumption state. As the power source weakens further, the power manager continues to place the camera into a lower and lower power consumption state, until the power source is exhausted. The method of the present invention preferably comprises the steps of monitoring the power source's voltage, generating a signal if that voltage falls below a pre-determined threshold, and reducing the camera's power consumption in response to the signal.

Abstract: A software object management system incorporated in a computer operating system utilizes a suite of transformations to convert objects between software object formats not native to an application program, and those which are a native software object type. In addition to formatting, transformations are also applied to change the location of an object and authenticate the object. With this approach, applications programs need not have the ability to handle any type of object other than their native types. The operating system does the transformations in a manner that is transparent to the application program. Additional transformations can be added to the operating system without modifying the application programs.

Abstract: In a digital signal processing system, a method for selecting a transform function to apply to an input signal based on characteristics of the signal, and for self-adjusting criteria which are used in selecting a transform function to apply to a subsequent signal. Characteristics are obtained from the signal. The characteristics are compared to adjustable criteria which are used in selecting a transform function. Differing criteria are maintained for the different selectable transform functions. A record is maintained of transform functions selected and the particular characteristics that caused the selection. Based on the ability of a transform function to minimally define the coded signal, an inverse transform function is selected to decode the signal. The criteria used in selecting a transform function to apply to a subsequent signal are adjusted based on a quality measure of the decoded signal and the record of selected transform functions.

Abstract: The present invention provides an improved method for memory accesses. The invention uses on an object referred to as a MemoryContainer object that contains the location and length of each memory transfer segment. An object referred to as a MemoryDescriptor object contains an index that locates the current position of the transfer and references one or more MemoryContainers. This separates the scatter-gather list and the processing information into two, independent, objects that are optimized for their particular task. Having separate containers and descriptors permits combining containers and descriptors into larger collections. When a client wants to start a memory operation, it provides the memory location. A MemoryDescriptor and a MemoryContainer are instantiated and returned to the server. The MemoryDescriptor asks the MemoryContainer for the number of ranges that the container has (usually one or more ranges).

Abstract: Improved techniques for charging batteries within portable computing devices are disclosed. The improved techniques operate to charge a battery at dynamically determined power levels. The power levels for charging the battery are dynamically determined by monitoring the power consumption of the portable computing device. When subsystems of the portable computing device are determining to be consuming less power than has been allocated thereto, higher levels of power from a power source are made available for charging the battery. As a result, the battery is able to be charged at a rate that is significantly faster than previously performed. Also, by dynamically monitoring the power consumption of the portable computing device, the improved techniques also ensure that the portable computing device will not be starved for power during its operation even as its subsystem's switch between normal (active) modes and low power modes.

Abstract: A method for labeling the pixels within a selected visual area of at least one image frame containing that visual area from a sequence of image frames stored in memory and operative to be displayed on an interactive display so that a user may subsequently select the selected visual area on a pixel accurate, frame accurate basis. To label the selected visual area within an image frame, the scene within that image frame is segmented to identify the selected visual area, each pixel within that selected visual area is then labeled with an area identifier which is unique to that selected visual area, and the pixels containing the area identifiers are mapped into an item buffer. The item buffer is then compressed and stored within a labeled portion of memory linked with the stored frame image from which the item buffer was derived.

Abstract: Relocation table entries in a executable object code file are interpreted as relocation instructions rather than as individual specifications for a particular respective relocatable information item. An abstract machine is provided for interpreting the relocation instructions and performing various relocation operations and various control functions for the abstract machine, in response to the relocation instructions. Certain variables contain information which is referenced and updated in response to certain types of the relocation instructions, thereby obviating the need to include such information as part of each relocation instruction. Certain of the relocation instruction types can also specify a particular relocation operation to be performed on a run of n consecutive relocatable information items, where n is specified as part of the relocation instruction.

Abstract: An electromagnetic pen digitizer is integrated into a flat panel display assembly using “bent TAB” active electronics. Integration is performed by placing a discrete electromagnetic pen digitizer further inside the flat panel display assembly itself behind the diffuser backlight component, but in front of the “bent TAB” active electronics. Interference from the active electronics is avoided because they are not in between the digitizer and the pen operating upon the flat panel display. The electromagnetic pen digitizer is integrated into the flat panel display assembly by inserting the digitizer into the flat panel display assembly behind the diffuser backlight during the routine manufacture of the flat panel display assembly.

Abstract: An extensible and replaceable network-oriented component system provides a platform for developing network navigation components that operate on a variety of hardware and software computer systems. These navigation components include key integrating components along with components configured to deliver conventional services directed to computer networks, such as Gopher-specific and Web-specific components. Communication among these components is achieved through novel application programming interfaces (APIs) to facilitate integration with an underlying software component architecture. Such a highly-modular cooperating layered-arrangement between the network component system and the component architecture allows any existing component to be replaced, and allows new components to be added, without affecting operation of the network component system.

Abstract: A method and apparatus for processing digital audio data comprises remapping channel status information in an input digital audio bit stream into a uniform format. The channel status information in the uniform format contains a super-set of data included in the channel status block of the original data and comprises a “higher level” form of presentation than the original status information, thereby reducing the amount of processing required by the application program in interpreting the audio data. The translation of audio data between different formats is performed in an interface unit. The interface unit strips the channel status information from the incoming digital audio data, translates the channel status information into a desired form, and then presents the audio data and the translated channel status information to a host computer for further processing or storage. The translation and routing functions performed by the interface unit are controlled by data stored in one or more registers.
