Title: Prepaid card
Inventor: RAMSBURG DOUGLAS
IPC: G07F7/10
Filed: 1997-12-15
Granted: 2002-05-07
Abstract: Debit cards, such as long distance telephone cards, may be attractively packaged and even readily mounted for point of purchase display, in such a manner that the card is inactive until activated at the point of purchase. T he card may be activated at the point of purchase without the necessity of in a ny way opening up the attractive packaging, or moving any portion of the packaging out of the way, and by merely "swiping" the card while still mount ed in the package through a conventional card reader. The card is mounted betwe en first and second panels of primarily cellulose material including an area significantly greater than that of the card, with the card magnetic strip completely exposed (that is uncovered by the panels or any other packaging material). The majority of the card is typically sandwiched between the firs t and second panels and is removably held to the panels, for example by hot me lt adhesive, and the panels are affixed to each other.

Abstract: This invention relates to methods for determining whether or not to discard a sample of oil based on the presence of polar compounds in the oil and devices to be used therewith. In a preferred embodiment a test strip comprising an adsorbent affixed to a backing is spotted with a polar indicator. A sample of oil is positioned on a heat conducting device supporting the test strip and the oil is allowed to migrate over the adsorbent material thereby displacing the polar indicator in an amount related to the amount of polar compounds in the oil. This displacement is correlated to the amount of polar compounds in the sample.

Abstract: A method and system for controlling downlink transmit power during a soft hand-off in a spread-spectrum wireless system supports independent power control of multiple forward channels to reduce fading. For a soft hand-off, a mobile switching center determines if a forward control channel is transmitted from different sectors of base stations than a forward data channel is. The base stations preferably adjust transmit powers of the forward channels grouped into different physical channels by receiving power control data over the allocated reverse power control channels to compensate for fading of the forward channels during a soft hand-off.

Title: Packet data communication system
Inventor: TYMES LAROY
IPC: H04L12/56
Filed: 1991-09-12
Granted: 2004-11-23
Abstract: A packet data transmission system is used to link a number of remote hand-held data-gathering units such as bar code readers to a central computer which maintains a database management system. Data packets are sent from the remote units by an RF link to intermediate base stations, then sent by the base stations to the central computer by a serial link. A method of selecting a frequency channel for RF window packet data communication is described. The method includes: (a) receiving signals by the base station on other channels different from an initially selected channel and producing a value for each of the other channels indicative of the RF energy level in such channel (i.e. to identify a channel having the lowest RF  energy level); (b) producing a value indicative of the transmission error rate in the initial one of the channels and (c) if the transmission error rate exceeds a threshold, sending a message from the base station to each of the remote terminals directing that transmission and reception of data packets between the base station and the remote terminals will change to the identified channel.
