Patent CA-2135144-C (CA)
Title: Digital brewer control
Inventor: KNEPLER JOHN T
IPC: G05B19/10
Filed: 1994-11-04
Granted: 1996-03-19
Abstract: A control system for a beverage brewing apparatus which includes a programmable control module and a separate input device.  The control system is used with a beverage brewing apparatus of the type having an infusion assembly for retaining and filtering a brewing substance, a heated water source and a water distribution system for transporting water from the heated water source to the infusion assembly. The programmable control module controls numerous adjustable functions associated with the brewer and stores at least one function limit for each of the functions which it controls. The separate input device is selectively attachable to the control module for manipulating the function limits of the programmable function retained and controlled by the control module.  Function controls are associated with the input device for selecting a function to manipulate and for incrementing and decrementing the limit or limits of the selected function.  The control module and input device allow selection of control limits which affect a valve for controlling water flow from the heated water source to the infusion assembly.  These control limits establish a dispensing cycle which periodically dispenses water from the heated water source through the water distribution system to the infusion assembly to prevent overflowing the infusion assembly.

Abstract: A novel method and apparatus for a two speed strap take up usable in a strapping machine. The two speed strap take up apparatus generally comprises ahigh speed roller assembly driven by a high speed drive shaft, a low speed roller assembly driven by a low speed drive shaft, a shaft rotation reduction assembly interconnecting the high speed drive shaft and the low speed drive shaft, and a roller clutch assembly interconnecting the shaft rotation reduction assembly and the low speed drive shaft. An input clutch assembly may interconnect the high speed drive shaft and an input drive means. In operation, a strap is disposed between and frictionally engaged by a high speed roller of the high speed roller assembly and a low speed roller of the low speed roller assembly. The low speed roller is then driven in rotation by the high speed roller. When a first tension is applied to the strap, the high speed roller slips relative to the high speed drive shaft until the roller clutch interconnecting the shaft rotation reduction assembly to the low speed drive shaft engages and rotates the low speed drive shaft at a reduced rotation rate relative to the rotation rate of the high speed drive shaft. The strap is now driven by both rollers at the reduced rotation rate as the high speed roller slips relative to the high speed drive shaft. When a second tension, greater than the first tension, is applied to the strap, the low speed roller slips relative to the low speed drive shaft at which time the strapping machine may perform additional functions on the strap.

Abstract: An antireflectance coating is disclosed comprising a first graded layer wherein the composition is varied throughout the thickness of the layer such that the refractive index of the graded layer varies from a low refractive index approximately matching the refractive index of the substrate at the interface of the graded layer and the substrate to a higher refractive index at the surface of the graded layer opposite the interface with the substrate, and a second substantially homogeneous layer of a composition selected to have a refractive index which is approximately the square root of the product of the higher refractive index of the graded layer and the refractive index of the incident medium at the surface of the second layer opposite the interface of the second layer with the graded layer, having an optical thickness of approximately at least one quarter of a selected design wavelength. The antireflectance properties of the coating can be expanded to a broader range of reflected wavelengths by incorporating, between the graded layer and the second substantially homogeneous layer, an intermediate layer having a relatively high refractive index and an optical thickness of about half the design wavelength.

Title: Packet data transmission in code-division multiple access communication systems
Inventor: SCHOTT WOLFGANG HANS
IPC: H04J13/00
Filed: 1995-06-14
Granted: 2002-05-21
Abstract: The present system is split into a physical layer (20), a data link layer, and a network layer (24). The data link layer is further split into three parts, namely, data link con-trol (23), and two medium access control parts (DLC) (21 and 22).    The DLC layer (23) is concerned with link establishment, release and maintenance. The lower MAC part (21) may exist in multiple instances, whereas the upper MAC part (22) is unique. Physically, the two MAC parts (21 and 22) are separated on the network side because the upper MAC part resides in a RNC while the lower part exists in each base sta-tion. The connectionless packet ser-vice (CLPS) entity (25.1) provides the packet radio service to the mobile user and the CLPS entity (25.2) on the netowrk side provides all facilities required for registration and authentication of mobile users, assigning and administrating their VCIs, and interfacing to a packet data network. The CLPS entities (25.1 and 25.2) use the logical link administrators (LLA) (26.x) to initially route messages via a regular dedicated control channel (DCCH) (27.x) to their peer entities. After the MS is attached to the PRCH, all messages exchanged between the CLPS entities (25.x) as well as user data packets are always directed via the respective PRCH (28.x). In this case, the control packets and user data packets an passed through the DLC (29.x) to the packet radio (PR) control entity (30.x). The packets are fragmented and protected with an error control code, e.g. a block code (BC), by a respective unit (31.x) for detecting transmission errors on the receiving side. Then they are convolutionally encoded, interleaved (IL) by the entity (32.x), and transmitted over the PDCH (33). On the receiving side the fragments are reconstructed from the received samples reassembled to packets, and forwarded to the target CLPS  entity (25.2). When the decoder (31.2) detects the receipt of an erroneous packet fragment, an automatic request for repetition (ARQ) scheme provided in the PR control requests its retransmission.
