摘要:
An embodiment of a media quantity sensing device and a media type sensing device includes a first, a second a third, and a fourth electrode. The first electrode is positioned above a media tray and the second electrode is positioned on the media tray below the media. The third and the fourth electrodes are positioned so that the media leaving the media tray passes between them. The media quantity sensing device further includes a measuring circuit coupled to a controller. The measuring circuit includes a first dual slope integrator to generate a first square wave output signal having a frequency dependent upon the dielectric constant of the media between the first electrode and the second electrode. The measuring circuit further includes a second dual slope integrator to generate a second square wave output signal having a frequency dependent upon the dielectric constant of the media between the third electrode and the fourth electrode. The measuring circuit also includes a frequency measurement unit to measure the frequencies of the first and the second square wave output signals. The controller reads the frequencies from the first and the second square wave output signals. The controller determines the media type in the media tray based upon the frequency of the first square wave output signal. Based upon the media type information, the controller selects and accesses a lookup table to determine the quantity of the media in the media tray by comparing the frequency of the second square wave output signal to values in the lookup table.

The flexible printing system is comprised of a printer that has printing characteristics that can be updated. A printer cartridge comprises printer data memory that either stores new printing characteristics or stores a location from the Internet from which these characteristics can be downloaded. The printer accesses the cartridge's printer data memory and checks the stored printing characteristics. If the printer can use these characteristics and they differ from the characteristics that are presently being used by the printer, the printer updates its printing characteristics using the printer data memory's printing characteristics. In one embodiment, the printer characteristics are color tables and dithering algorithms.

A consumable order-assistance system is provided for computer peripheral devices. The system includes a personal computer, at least one computer peripheral device, and a user interaction site. The personal computer has a messaging system. The at least one computer peripheral device has a messaging system. The communication link signal couples the personal computer with a provider of a consumable for the computer peripheral device. The user interaction site is configured to receive a notification from the computer peripheral device via the messaging system of a need to order a consumable. The user interaction site is provided within one of: a single-connection environment as an end user interface; an unmanaged network environment as a workgroup administrator interface; and a server-based centralized network environment as a centralized system administrator interface. A method is also provided.

Methods and apparatus for locating a network device relative to other network devices are useful for the management of wireless computing networks. Signal strength in a wireless network is indicative of a distance between a transmitting device and a receiving device. Through use of triangulation of the received signals at multiple receiving devices, the relative location of the transmitting device can be determined. Methods of refining the estimation of the expected location of the transmitting device are further provided. Defining an absolute location for at least one of the devices will permit determining the absolute location of the remaining devices based on these relative locations. Locating network devices relative to each other facilitates identifying a closest available resource within the network.
摘要:
A printing system utilizes printing material cartridges with memory to provide a way to uniquely identify the contents of a printing device cartridge and optimize printing parameters for use with the printing material. Newly developed printing materials and printing solutions therefor can be provided to printing devices that were manufactured prior to the development of the new printing material. Additionally, all cartridges can be physically similar without regard for the type of printing material contained therein, so no special manufacturing is required for each different printing material.

Methods and apparatus for generating notifications associated with the lifetime of peripheral unit consumables are described. In the described embodiments, users or clients are able to define and adjust their own threshold values that are associated with a consumable's lifetime. In one embodiment, a lifetime monitoring mechanism is provided and monitors the lifetime of a peripheral unit consumable that is associated with operation of the peripheral unit. The lifetime monitoring mechanism is configured with a user-manipulable, threshold-defining mechanism that is configured to receive user input and, responsive to the user input, define a threshold value for the lifetime monitoring mechanism. The peripheral unit's use of the consumable is monitored using the lifetime monitoring mechanism. A determination is made when the peripheral unit's use of the consumable reaches the threshold value and, responsive thereto, a notification is generated.

A thrust rod anchor for utilization in conjunction with a tied form of pipe joint restrainer system. The anchor utilizes two arcuate band segments the ends of which are welded to elongate junction devices such as blocks. These junctions are bolted together in the course of assembling the anchor over the outside surface of a pipe. The assemblage of junctions and arcuate band segments support thrust rod connectors having apertures formed in thrust plates thereof advantageously spaced outwardly from the band segments. Spaced away from the thrust plates of each connector are pairs of set screws. A buttress arrangement is utilized to support the thrust plates of the tie rod connectors. The anchor assemblies have been shown to provide enhanced anchoring resistance to thrust forces and to be more facilly mounted upon a pipe surface.
