  • Publication number: 20240151417
    Abstract: Systems/methods for intelligent commissioning of an HVAC system provide a control node and at least a first network node coupled to communicate with the control node, the first network node configured to retrieve via a user interface objects configured at the control node, configure at least a second network node using the retrieved objects, and report the configuration of the second network node at the control node. A user interface of a first network node can access the objects at the control node. The first network node can apply the accessed objects to configure a second network node using a commissioning tool. The commissioning tool can be activated specifically for certain authorized HVAC personas or roles. The first network node can report the configuring at the control node. The commissioning tool can be voice-enabled to allow a single user to configure the HVAC system via voice commands.

  • Publication number: 20100005004
    Abstract: A preferred method for providing a guarantee for a value of product includes the steps of receiving product information, generating a product value based on the received product information, and providing a guarantee that a user will receive a payment for a product, the payment having a value at least equal to the generated product value. A preferred system for generating a product value includes a user interface adapted and configured to receive product information; a processor coupled to the user interface, wherein the processor is adapted and configured to generate a product value based on the product information received by the user interface; and a payment having a value at least equal to the product value. The system and method are preferably designed for the ecommerce field and, more specifically, for guaranteeing a selling price of a product in the ecommerce field.

  • Patent number: 6778294
    Abstract: A color printer receives N-bit values indicating a computer generated color to be printed. Each N-bit value has a most significant bit (MSB). Upon receiving the N-bit color values, the color printer creates an address from combined multiple-bit segments of each of the received N-bit values, each multiple bit segment includes at least a MSB of each N-bit value. The color printer includes a cache memory, each cache address including first and second entries. The first entry being values indicative of a computer generated color and the second entry being values usable by the color printer to reproduce a color indicated by the first entry. A processor determines if there is a match at an address created from a received computer color value between the first entry and the received computer color value. The processor is responsive to a determined match to access the second entry at the address and to employ the second entry to control the color printer.

  • Patent number: 6690489
    Abstract: A graphics language interpreter includes one or more color converters that accept input color values and that algorithmically convert such input color values to output color values. The color converters are specified by a standard that defines the predefined graphics language. The color converters use color conversion algorithms that are potentially specified by graphics commands during rendering. A lookup component is associated with the color converters. The lookup component indicates output color values corresponding respectively to selected input color values. The lookup component is initialized with output color values that are converted from the selected input color values by the converters. During rendering, the graphics language interpreter uses the lookup component rather than the one or more color converters to convert input color values to output color values.
