Abstract: A robotic cleaner includes a housing, a suction conduit with an opening, and a leading roller mounted in front of a brush roll. An inter-roller air passageway may be defined between the leading roller and the brush roll wherein the lower portion of the leading roller is exposed to a flow path to the suction conduit and an upper portion of the leading roller is outside of the flow path. Optionally, a combing unit includes a plurality of combing protrusions extending into the leading roller and having leading edges not aligned with a center of the leading roller. Optionally, a sealing strip is located along a rear side of the opening and along a portion of left and right sides of the opening. The underside may define side edge vacuum passageways extending from the sides of the housing partially between the leading roller and the sealing strip towards the opening.

Abstract: An integrated amine and redox gas treatment system is configured to treat an influent hydrocarbon containing stream. The system includes a reduction oxidation unit connected directly downstream of an amine unit. The amine unit is configured to separate the influent fluid stream into a first amine effluent stream including hydrocarbons and a second amine effluent stream including a connection pressure and comprising CO2. The reduction oxidation unit is configured to receive the second amine effluent stream from the amine unit and operate at the connection pressure while releasing a reduction oxidation effluent stream including purified CO2. The connection pressure includes a single pressure or a plurality of pressures at which both the amine unit and the reduction oxidation unit are configured to operate.

Abstract: An instant access guitar system allowing easy access to cavities in the body portion of the electric guitar. The cavities are covered by plates, a pick guard, flexible laminates or other suitable cover materials. The covers are held in place by (1) cut-outs in the guitar body and (2) magnets that magnetically attach to magnetic material mounted in the guitar body. The appearance of the guitar may be changed by changing the pick guard and the decorative laminate on the headstock. The sound of the guitar may be changed by having unique pickups and wiring releases pre-built in multiple configurations on multiple pick guards as modules to change in and out of the guitar at will with no tools or solder.

Abstract: A computer system implements a standard modem without the use of a microcontroller. Instead, a digital signal processor is provided on an expansion card, but with direct links to the computer system itself. The code usually implemented in the microcontroller is instead implemented as a virtual modem controller to be called by the operating system of the computer itself. Further, this virtual modem controller includes a virtualized UART, that appears to the operating system software as a hardware UART, with entry points for calls to replace input/output instructions. In this way, standard device driver code written to execute input/output operations is easily converted to operate with the “virtualized” UART.

Abstract: A system and method for enabling multi-path functionality between a host bus adapter (HBA) in a host computer of a storage system and at least one storage device is disclosed. The host computer includes a processor and associated memory, and an operating system including a PnP manager that maintains a logical device stack for the storage device. An HBA-specific filter driver intercepts responses from the underlying HBA driver to specified PnP requests. These responses are modified to prevent standard Microsoft operating system SCSI class device drivers from being loaded for devices attached to the HBA. Instead, the modified responses cause a multi-path SCSI class device driver to be loaded. The filter driver also monitors the status of the paths to a device and, upon request, provides status information to the multi-path SCSI class device driver. The multi-path SCSI class driver may use this status information to decide whether to make a particular path a primary path.

Abstract: An electrically isolated high speed optical switching arrangement for use as a computer over-voltage sensing circuit utilizing first and second optoisolator devices, the first having an input, a first signal from the output of a bus sensing circuitry which provides two complementary outputs, with the output voltage of the optoisolator controlling power-down circuitry for the computer in response to an over-voltage condition. A second control optoisolator has its output in parallel with a resistor in the base to emitter path of the first optoisolator. The complementary signal of the bus-sensing circuitry provides the input to the second optoisolator. During normal power conditions, the first optoisolator is conductive and the second is non-conductive.

Abstract: Glycoproteins, especially glycosylated hemoglobins, are separated from non-glycosylated proteins, by complexing with a dihydroxyboryl reactive agent. The resulting complex can be separated physically from the non-glycosylated protein, making possible the determination of glycosylated hemoglobin content of lysed blood; a reactive agent and a kit are described for use in such determination and as a monitor in the control of diabetic treatment. The invention can also be used preparatively to isolate glycoproteins.
