Title: Method and apparatus for extraction of marine sediments
Inventor: ERIKSSON LARS L
IPC: B09C1/00
Filed: 1995-04-07
Abstract: A freezing cell having one or more freezing tines may be used to remove contaminated sediment from the beds of water bodies. The freezing tines are to be immersed into the sediment. Refrigerant is supplied to the tines by a refrigeration unit during the freezing cycle to solidify the surrounding sediment into a block held by the cell. The block of frozen sediment is lifted from the water body. The block is released from the freezing cell by heating the tines. The block is then transported for treatment. The freezing cell may be returned for reuse in sediment removal. The freezing cell may be configured to permit close placement of the cell to other like cells used in the extraction process. A method of freezing marine sediment into blocks is used to recover contaminants from water bodies.

Abstract: In a DS/CDMA receiver, each of first and second receiving units (211 and 221) receives a DS/CDMA signal as a received signal. First and second adaptive interference cancellers (212 + 213, 222 + 223) are connected to the first and the second receiving units, respectively.      Each of the adaptive interference cancellers cancels an interference on they received signal. Connected to the first and the second receiving units and to the first and the second adaptive interference cancellers, a single interference canceller control circuit (204) controls the first and the second adaptive interference cancellers in common. An all output. combiner (201) combines all of output signals of the first and the second adaptive interference cancellers. Preferably, each of the adaptive interference cancellers has an adaptive filter (212 or 222) to cancel. the interference with respect to all other stations by adaptively making its tap coefficients orthogonal to spreading codes of the all other stations. Each of the adaptive interference cancellers further has a differential detection circuit (213 or 223) to compensate for phase fluctuation of an output signal of the adaptive filter. The single interference canceller control circuit may control the adaptive interference cancellers in common on the basis of best quality control information relating to one of the received signals of the first and the second receiving units that has a best signal quality.

Title: Method and apparatus for protecting circuitry accessible through metallic contacts from static discharge damage
Inventor: MESSINA SEBASTIAN J JR
IPC: H02J7/00
Filed: 1996-04-15
Abstract: Electro-static discharge protection for sensitive circuitry in devices, which have exposed metallic contacts for accessing such circuitry, is achieved by providing switching apparatus in these devices. The switching apparatus isolates the sensitive circuitry from static electricity which may be impressed upon the exposed metallic contacts. In operation, when a first device is placed in engagement with a second device for transferring data, charging a battery or the like, the switching apparatus relies on the weight exerted by the first device on the second device for establishing a conducting path between the contacts and the sensitive circuitry in each device. This conducting path is interrupted when the first device is removed from the second device thereby providing isolation for the sensitive circuitry from any static electricity which may be impressed upon the exposed metallic contacts. The switching apparatus also is configurable for establishing a conducting path from the contacts on each device to ground potential whenever the first device is removed from the second device. The ground potential conducting path provides additionalprotection for the sensitive circuitry against electro-static discharge damage.
