Abstract: A flash memory controller operates a flash memory array comprising a plurality of different types of flash memory chips. The CPU interacts with the array by issuing generic commands through a single Memory Technology Driver (MTD), while the controller translates the generic commands into commands specific to the chip comprising the portion of the array being addressed. The controller operates each of the flash chips which comprises the flash memory array, and presents to the CPU a memory system comprised of a single addressable entity. According to a further feature of the invention, the controller is embedded into each of the flash chips in an array in order to further reduce overhead costs.

Abstract: A balloon kit package is provided to facilitate erection of a balloon assembly in a desired manner so as to prevent unintentional loss of buoyant balloons. The kit package includes an uninflated balloon, a placard greeting card or other object of mass sufficient of mass to overcome the buoyancy of the balloon when inflated and articles such as a ribbon for joining the balloon to the placard. In an alternative embodiment, the neck of the balloon is inserted directly into the placard. In package form the balloon kit is sealed in a plastic overwrap.

Abstract: A system and method for communicating accounting and billing operations information between a gateway mobile switching center (G-MSC) and a visiting mobile switching center (V-MSC) to which a call is being directed to a mobile station within a cellular telecommunications network. The method comprises the steps of: generating in the serving MSC first billing identification data for the call; transmitting the first billing identification data to the destination MSC; generating second billing identification data in the destination MSC corresponding to a call transaction that has occurred in the destination MSC; and returning the second billing identification data as related billing identification data to the serving MSC after an outcome for the call has been determined in the destination MSC. The outcome of the call is determined when a page response has been received in the V-MSC from the mobile station or alternatively, a call has been delivered by seizing a trunk from the serving MSC to the destination MSC.

Abstract: Ferrous powder particles are coated with vaporized phosphorus in a fluid-bed reactor to obtain homogeneous coatings of phosphorus. The coated powders are useful feed for pressed structural parts, exhibiting improved green density, compressibility and sintered density thus improving magnetic and tensile properties.

Abstract: A cellular communications system including a mobile station that shifts periodically between a stand-by operating mode where communications are possible and a deep sleep operating mode wherein communications are impossible and battery power is conserved. Thus, while the mobile station is in deep sleep mode, message transmissions to the mobile station are impossible. The messages are, however, stored for later delivery, and a record of the stored, undelivered messages is maintained for future access. When the mobile station emerges from deep sleep, the maintained message record is checked, and the stored messages for the awakened mobile station are retrieved and delivered.

Abstract: An improved method for scrubbing a substrate, the method including the step of scrubbing one face of the substrate with a cylindrical rotary brush while applying back pressure to the substrate by jetting a fluid for generating back pressure against the other face of the substrate.

Abstract: A retainer is provided for a face piece that has a generally triangular face shaped rim for forming a seal over user's face when the face piece is worn. The retainer is made from a stiff material and has a rim that conforms to the rim of the face piece, and is shaped to provide a loose frictional fit over the face piece. The retainer helps protect the face piece during shipping, storage, and when otherwise not in use, and can help correct minor deformation in a face piece.

Abstract: The load on the communications resources of a cellular telephone system is monitored to detect instances of excess amounts of unused resource capacity. When such instances are detected, a message is transmitted to subscribers via the cellular system offering reduced charging rates for calls initiated in response to the offering message. The subscriber mobile stations are programmed to alert the subscriber to the broadcast of the offering message, after which the subscriber may initiate a reduced rate call. The mobile stations may further be programmed to automatically initiate the cellular call in response to receipt of the offering message, and to thereafter engage in the communication. Monitoring of communications resources external to the cellular system is also made, and an offering message is broadcast by the system in response to detection of excess amounts of unused external resource capacity, in response to which subscribers may initiate calls requesting reduced rate access to the resource.
