Abstract: A cashierless shopping store (10) including portable RF shopping terminals (34) carried by shoppers. Bar codes on purchased items are scanned using a RF shopping terminal before being placed in a shopping cart (210). The shopping cart detects the weight of items placed therein and conveys the weight information to the RF shopping terminal over an RF communications link. The RF shopping terminal compares the weight information received from the shopping cart with the weight information read from the bar codes. If the weight information does not correlate, the RF shopping terminal signals a controller (52) to activate an alarm. When the shopper wishes to pay for the purchased items, the shopping cart is wheeled to a cashierless checkout station (24). A lifting unit (304) lifts the shopping cart to detect the weight of the purchased items and conveys the weight information to the RF shopping terminal. The RF shopping terminal again compares the weight information received from the lifting unit with the total weight information read from the scanned bar codes. If the weight information correlates, the RF shopping terminal prompts the shopper to enter a debit, credit or smart card into a card reader therein. Once the card is read, the RF shopping terminal prompts the shopper to enter a PIN or password and then generates a financial transaction request. The financial transaction request is conveyed to a network controller (314) over an RF communication link. The network controller in turn conveys the financial transaction request to a financial institution for verification and processing. Once processed and verified, a verification is transmitted back to the network controller which in turn signals a printer (318) to print a receipt and open a gate allowing the shopper to leave with the purchased items.

Abstract: A System for enabling a PC card (10) to approximately function in the 16-bit and 32-bit standard PCMCIA environments. If the 16-bit standard and the 32-bit standard requires a pin to be connected in a certain manner, then the pin is connected in that manner. If the 16-bit standard requires a card detect pin (24) to be grounded and the 32-bit standard requires that same card detect pin (24) to be connected to a voltage sense pin (26), then the card detect pin and voltage sense pin are connected (26), and the card detect pin (24) is connected to ground via a pull-down resistor. After initialization, the standard of the PCMCIA adapter (12) can be detected by sensing the voltage of an open-circuited voltage sense pin.

Abstract: An air isolation hand covering (10, 50, 120) has a bladder (11, 81, 124, 150, 160, 170, 180, 200, 220) consisting of a plurality of interconnected or independent inflation cells (85, 112, 210) that is positioned between the hand and a hand-held tool or other vibrating object. The cells (85, 112, 210) are oriented to permit easy bending of the hand covering (10, 50, 120) in directions appropriate for grasping an object. The effectiveness of the bladder in reducing the vibration energy transmitted to the hand is a function of the shape and configuration of the bladder, the pressure in the bladder, the compressible fluid used, the volume of the bladder, and the grip force and push force used when clasping a tool or other object. The bladder (11, 81, 124, 150, 160, 170, 180, 200, 220) can be filled with air or other fluid during the fabrication of the bladder or it can be inflated or deflated with a small pump (28, 128) and integral air valve (29, 134) connected to one of the air cavities (85, 112, 210).

Abstract: A digital mobile communication system has a high-speed non-transparent data connection between a transmitting and a receiving party (MS, TAF). For the data connection, parallel subchannels (chl-chn), corresponding in number to the nominal data transfer rate, have been allocated on the radio interface. A radio link protocol (RLP) is responsible for transmitting data over the radio interface, and for acknowledging correct data frames and for retransmitting defective data frames. A transmission buffer (63) buffers the data frames to be transmitted and stores the data frames transmitted until it receives an acknowledgement of successful reception. In order to reduce interference and power consumption, user data is transmitted by using as many of the allocated subchannels as required by the actual user data rate at any one time. On the other allocated subchannels, transmission is interrupted or discontinuous transmission is activated.

Granted: 2010-02-23
Abstract: The invention relates to a method for recovering nickel and other valuable metals and for precipitating iron from two pyrometallurgically produced nickel mattes, one of which contains a smaller proportion of iron that the second matte. The leaching of iron-bearing nickel matte is carried out in at least one atmospheric leaching step and at least one pressure leaching step by using a leaching solution from the leaching cycle of a less iron containing matte into the leaching of a more iron containing matte at a stage where the iron of the less iron containing matte is in soluble form. The iron contained in the mattes is advantageously precipitated as jarosite and the solution created in the leaching of the more iron containing matte is conducted back into the leaching cycle of the less iron containing matte.

Title: Electronic apparatus

IPC: H01L23/427
Filed: 1999-01-25
Granted: 2002-09-03
Abstract: Electronic apparatus is contained in a heat dissipative external enclosure. The enclosure contains at least one unit contained in a thermally conductive internal housing providing RF isolation and mounted on a wall of the enclosure in thermal contact therewith. A wall of the unit has a first recess receiving the evaporator of a heat pipe. The heat pipe is clamped between the external enclosure and the internal housing.      The condenser of the heat pipe is lower than the evaporator and is received by a recess in the wall. The evaporator is clamped in the recess by a clamp member e.g. another unit. Because the heat pipe is clamped at its ends, it does not need to be an interference fit in either recess and may thus easily be removed. The inner housing can maintain RF isolation.

Abstract: A high speed analog-to-digital converter utilizes a fine resolution ADC to digitize the low band component of an analog video signal to produce a fine resolution signal and a coarse resolution ADC to digitize the full spectrum of the analog signal and produce a coarse resolution signal. The coarse resolution signal is subtracted from the fine resolution signal to generate a summed signal containing a quantization error, which is filtered through a low pass digital filter to filter out the high band component and pass the quantization error. The filter output is summed with the coarse resolution signal to restore the fine resolution of the low band, producing a digital output signal that has a resolution suitable for high definition applications.
