Abstract: A system for controlling the impedances of circuits on an integrated circuit chip is provided. At least one circuit is selected to operate as a p-channel reference circuit, and at least one circuit is selected to operate as an n-channel reference circuit. Other circuits are selected to operate as circuits and/or line termination circuits. A digitally controlled impedance (DCI) circuit controls the p-channel reference circuit to determine a desired configuration of p-channel transistors for use in the circuits. The DCI  circuit further controls the n-channel reference circuit to determine a desired configuration of n-channel transistors for use in the circuits. The DCI circuit takes into account such factors as resistances of p-channel transistors in the p-channel reference circuit, resistances of n-channel transistors in the n-channel reference circuit, as well as temperature, voltage and process variations. The DCI cirucit relays information identifying the desired configurations of the n-channel and p-channel transistors to the circuits. The circuits are then configured in response to this information.

Abstract: It is an object to provide an automatic banding packing machine capable of easily removing the ring of a band with a simple structure when idle banding is carried out. When the rear end side of a band is to be pulled back by band pull-back means (84), an amount of the pull-back is detected by detecting means. It is decided that idle banding of the band is carried out when a result of the detection is greater than a preset length and the band is wound around a slide table. Thereafter, the rotation of a cam shaft (41) is temporarily stopped based on a signal, whereby the timing of the pressing to be carried out by a middle presser member, which is operated after melting the superposing portion of the band by means of a heater (36), is delayed in a predetermined time.

Granted: 2010-04-20
Abstract: A vaporizer device that uses a flame (46) for vaporizing flavor and psychoactive compounds from smoking materials such as tobacco (28). The present device has a filter unit (34) with a porous flame filter (36). The flame filter (36) can be made of open-cell ceramic or metal foam, sintered ceramic or metal granules or other porous, heat resistant materials. In use, flame (46) is supplied to the flame filter (36), and inhalation causes ambient air to enter the flame filter (36) as well. The flame exhaust and ambient air are mixed within the flame filter (36) and produce an air stream of intermediate temperature. The intermediate temperature air stream is hot enough to vaporize desirable components from the smoking material (28), but generally is not hot enough to burn the smoking material (28). The temperature of the air stream can be controlled by adjusting the amount of flame (46) supplied to the flame filter (36).

Abstract: A method and system for quality-based transmission power control in a cellular communications system are disclosed, whereby a network operator can specify the transmission quality requirements using a measurement that better reflects the actual quality perceived by the users. All transmitter'power levels in the network can be controlled by identical power regulators, each of which can adapt to individual traffic situations in order to achieve the specified quality. For example, in a GSM frequency-hopping network, the FER together with the parameters estimated from the current traffic situation, are mapped onto a target C/I, which in turn, the power control algorithm strives to achieve. Consequently, the power regulators can adapt to the traffic situation experienced by each receiver.
