  • Patent number: 6596774
    Abstract: The present invention is the synthesis of a series of 1,5-dichloro-9(10H)-anthracenones bearing O-linked and N-linked substituents in the 10-position. These compounds were evaluated for their ability to inhibit the growth of the human oral epidermoid carcinoma cells (KB cell line), human cervical carcinoma cells of ME 180 (GBM 8401) and Chinese hamster ovary cells (CHO), respectively. In addition, redox property of the compounds for inhibition of lipid peroxidation in model membranes was determined.

  • Patent number: 6590451
    Abstract: A complex baseband model of the power amplifier within a DSP domain is used to develop a feedback signal that would be equivalent to the optimum negative feedback used for the analog amplifier. Once the feedback signal is available, it can be processed to compensate for the effects of the group delay and for optimum loop gain, hence resulting in a broadband response with no theoretical limitations on the linearization of the amplifier.

  • Patent number: 6564455
    Abstract: A method of making a socket test probe which results in a probe head which has flat plates which serve as electrodes encased in resin. The electrodes are conductive plates with one or more edges of the conductive plates exposed for connection to the electrodes of a socket. The entire probe head starts as a solid block of conductive material which is drilled, machined, filled with resin and machined again to form a socket testing probe utilizing the edges of conductive plates as electrodes.

  • Patent number: 6561439
    Abstract: A dual closure nozzle for use with a hose carrying a liquid under pressure. The dual closure nozzle is made up of an inner delivery conduit attached to an end cap and threaded within an outer sleeve. The nozzle is configured to have two different stop positions and to be adjustable between these two stop positions and a variety of open positions. When a liquid is forced through the nozzle, the flow of the liquid can then be adjusted from a first stop position, where no liquid passes out of the nozzle, through a variety of open position spray patterns to a second stop position. This configuration thus provides a nozzle that can be closed by turning the outer sleeve portion of the nozzle in either of two directions.

  • Patent number: 6560165
    Abstract: A medical information appliance which reminds a user of times to take medications or to perform medical-related activities. It features a delay mode, which shuts the alarm off but later reminds the user to take the indicated medication. Multiple alarms can be set for a variety of medications or other medical events, and multiple delay modes will be activated, so that the user is reminded to take medications which have been indicated by an alarm, but taking the medication was not confirmed by the user. The device also features a readout button for displaying stored medical information, for use by medical technicians in the field without connection to further equipment.

  • Patent number: 6556927
    Abstract: A sensing device for detecting and identifying vehicles or other events which apply force to a roadway or other structure. The force applied by a vehicle is interpreted to produce a force signature which is unique to a vehicle, and thus can be used to identify individual vehicles. Other force events which can detected and identified include pedestrians, motorcycles, avalanches, roadway deterioration, structural failure of bridges or other structures, avalanches, bicycles, and railroad trains.

  • Patent number: 6550347
    Abstract: The invention is an air sampler which utilizes a hydrophobic filter and an entrapment fluid contained within a sampler body. Air to be sampled is bubbled through the entrapment fluid, which traps and retains a selected air component for later testing. Air which is thus bubbled through the entrapment fluid passes through a hydrophobic filter before leaving the sampler body. A hydrophobic filter prevents aqueous liquids from exiting the sampler body. This allows a higher rate of air flow, because the sampling fluid does not diminish as quickly due to suspended droplets exiting the sampler body. The sampler body may also be inverted to rinse down the walls of the sampler body without losing any liquid, due to the presence of the hydrophobic filter. The entrapment fluid can be poured or drained out of the sampler body.

  • Patent number: 6547771
    Abstract: A non-invasive female urinary device allows a woman to urinate in a standing or sitting position. The non-invasive female urinary device provides a scoop portion designed to be positioned adjacent to the woman's body, and is sized to fit between the labia majora. The scoop gathers urine as it is produced, with little or no loss due to spillage. A generally tubular body is attached at an upstream first end to the scoop portion. The device is made of six flat sides to allow the woman to control the orientation of the device. The logo on one of the sides provides a tactile reference, allowing the woman to orient the device without the need for visual input. A flow concentrator is attached to a downstream second end of the tubular body, and has a generally rectangular opening that narrows the stream of urine to result in a smooth and continuous stream.

  • Patent number: RE38211
    Abstract: The invention is a dual reel cord take-up device for flat wire cable which as a generally semi-cylindrical upper and lower case half which snap attach together over a dual-purpose shaft to make two compartments. The first compartment is a cord extension and take-up compartment which is divided in two by a slotted disk on the dual-purpose shaft in that compartment. Flat wire cable is wound on the dual-purpose shaft in both compartments, and extends through two apertures in the walls of the compartment. The cable in one aperture is fixed so it does not move in and out of the aperture. The wire cable in the second aperture is free to extend or retract through the aperture. A spring provides the power to retract cable into the take-up device.
