Abstract: A method and apparatus for forming a beverage. A brewer may be operated so that when water or other beverage precursor is detected to be heated to a desired temperature, the liquid may be provided to a brew chamber to form a beverage. In one embodiment, detection of the water temperature may be performed by a temperature cut off switch (TCO) which is normally closed to provide power to a water heater, but opens when the water reaches a predetermined temperature. Opening of the TCO may cause delivery of the liquid to the brew chamber, e.g., by causing pressurization of a reservoir containing the liquid. In another embodiment, control of delivery of water from the reservoir may be made based on power interruption to the heater. For example, an air pump may be controlled to deliver air to the reservoir in response to power to the heater being cut off.

Abstract: A method and apparatus for forming a beverage. An access opening for a reservoir of a brewer may be opened (e.g., to allow a user to provide liquid into the reservoir for forming a beverage), and thereafter, the access opening of the reservoir may be closed and the reservoir pneumatically sealed. The access opening may be closed and the reservoir pneumatically sealed by closing a lid of the reservoir, e.g., by a user pressing down on the lid. Pneumatic sealing of the reservoir may allow the water in the reservoir to be expelled from the reservoir for flow to the brew chamber by introducing air pressure into the reservoir, e.g., by an air pump. The reservoir may be vented during heating of the water, and during pressurization of the reservoir for delivery of the brew water.

Abstract: A beverage forming system includes an actuator and first and second portions that are movable relative to each other between open and closed positions. The first and second portions include a cartridge receiving portion to accept a cartridge for forming a beverage, e.g., a disposable single serve cartridge. A first linkage member may be fixed to the actuator and physically contact a second linkage member that may be fixed to the first or second portion (or to a frame that supports the first and second portions). Movement of the actuator may cause movement of the first and second linkage members relative to each other, thereby causing relative movement of the first and second portions between open and closed positions.

Abstract: A method and apparatus for controlling a pump adapted to cause liquid to flow from a first location to a second location. The pump may be operated in a calibration period, and based on performance characteristics for the pump, an operation index may be assigned to the pump. The operation index may be used to control subsequent operation of the pump. For example, the operation index may be used to identify an operation time for the pump to deliver a predetermined volume of liquid. Performance characteristics used to determine the operation index may include a voltage supplied to the pump and/or a volume flow rate of the pump.

Abstract: An interconnection unit for connecting multiple data processing systems in a distributed data processing network. The interconnection unit comprises a single controller with control and data sections that connect to each data processing system in the network through an interface circuit and a host processor interface circuit that connects to each data processing system. For one data processing system to transfer information to an other system, the one system requests exclusive control of either the data or control section of the interconnection unit. Each section independently and sequentially tests each interface circuit to determine if a control request exists. When a section grants a request, the requesting data processing system transfers information to or from a memory in that section associated with another system in the network. That memory is accessible to all the data processing systems.

Abstract: A display unit useful for displaying graphical information and specifically for composing items to be printed on a page. The display unit includes a dot matrix screen and a display memory for storing the information to be displayed. An addressing register identifies memory locations in a sequence starting at location established by a begin display register. The starting location is transferred to the addressing register each time the display unit reaches a first dot location in the display unit. If the starting location is changed, an image corresponding to the item stored in the memory moves on the screen as a unit. Two or more memories can be interconnected to enable a relative motion between images corresponding to the items stored in each display memory.
