Abstract: An air freshener device comprises one or more planar elements that can move relative to a base, where each planar element is connected to the base by a flexible connector, and where each planar element releases a fragrance. The planar elements and the flexible connectors are disposed in a plane. The planar elements may be made of an inexpensive paper material and may bear images or text. The air freshener device imparts fragrance to an area and has moving parts that entertain viewers and also attract the attention of viewers. When mounted in an automobile, for example, the device can entertain child or adult passengers. The device can also convey a statement, using images or text, to drivers of nearby automobiles, who will notice the device because of its motion.

Abstract: A shower pan includes a draining base portion that drains to an orifice. The draining base portion includes a support structure for supporting a slab floor member (for example, a single piece of granite, marble, or engineered stone) above the orifice such that a planar upper surface of the floor member has a slight tilt. The pan is installed such that the tilt is toward a shower head. The shower enclosure is finished by cladding the enclosure walls with a finishing material (for example, granite, marble or engineered stone) such that the finishing material extends down into the pan. The floor member is placed on the support structure such that water from the shower head that falls on the floor member runs off one or more edges of the floor member and is conducted to the orifice under the floor member by a draining portion of the draining base portion.

Abstract: A portable tire prep detector is used to detect prep on a tire, when the tire is on a racing vehicle, and when the racing vehicle is on a race track. In one example, the detection of prep using the portable tire prep detector involves a test that takes less than two minutes. Multiple tires can be reliably tested in this way in rapid succession, even if some of the tires tested cause large amounts of prep to be drawn into the portable tire prep detector. In one example, the portable tire prep detector is a portable gas detector involving a catalytic combustion sensor. The portable gas detector is able to detect very low concentrations of hydrocarbons in a sample gas drawn into the detector from the tire surface. If the detector reads above a predetermined threshold value, then the tire is determined to have been prepped.

Abstract: A non-structural shear wall nailing template bears a pattern of shear wall nailing pattern markings. The template is made of an inexpensive sheeting material that will not interfere with the further construction of the building if the template remains in-situ after construction of the shear wall. In one example, the template is a strip. The strip bears lettering that indicates the type of nailing pattern to which the nailing pattern markings conform. After fixing the template to one or more sheathing panels such that the template is aligned in a predefined way with respect to framing members behind the panel(s), nails are driven at the locations of the markings on the template. By driving a nail at the location of each template marking, the shear wall is constructed with proper nail spacing. A set of templates is provided to facilitate nailing in different shear wall nailing patterns.

Abstract: A power supply device that is capable of outputting multiple different output voltages is coupled by a DC power supply cord to an electrical device. An unpowered memory in the electrical device stores information about the power requirements of the electrical device (for example, the DC supply voltage required). In a first time period, when the power supply device is not powering the electrical device, the power supply device sends an energizing pulse train across the power cord. The electrical device captures energy from the pulse train. In a second time period, the electrical device uses the captured energy to transmit the information back to the power supply device across the power cord as pulses. The power supply device uses the information read back from the electrical device to output the appropriate DC supply voltage for the electrical device onto the power cord.

Abstract: The spam blocker monitors the SMTP/TCP/IP conversation between a sending message transfer agent MTA—0 and a receiving message transfer agent MTA—1; catches MTA—0's IP address IP—0, MTA—0's declared domain D—0, sender_address A—0; and recipient A—1; and uses this source and content based information to test for unsolicited messages. It interrupts the conversation when MTA—0 sends a command specifying the recipient (an “RCPT” command) and uses the various test results to decide if the message is suspected of being unsolicited. If the message is suspected of being unsolicited then it logs the rejected message, sends an error reply to MTA—0 which forces MTA—0 to terminate the connection with MTA—1 before the body of the message is transmitted; else it logs the allowed message, releases the intercepted RCPT command which allows the conversation between MTA—0 and MTA—1 to proceed.

Abstract: A high speed socket includes an insulative housing and a printed circuit board body portion. The PCB body portion includes a PCB and surface mount contacts. Each surface mount contact has a first end portion for making contact with an integrated circuit held in the socket and a second end portion for surface mounting to a printed circuit board. The socket's printed circuit board includes AC grounded conductive columns (ACGCC) that extend from a first planar surface of the PCB to a second planar surface of the PCB. The printed circuit board also includes signal conductors. The signal conductors are shielded by the ACGCCs. In one aspect, the socket includes capacitors that are surface mounted to the socket's PCB. In another aspect, the surface mount contacts include self-adjusting solder tails that accommodate PCB warpage.

Abstract: Memory access bandwidth within a digital camera is allocated among several requestors by assigning each requester a “tokens per snapshot” (TPS) value. Each requestor has a DMA engine and a DMA entry queue. If the requester wishes to access the memory, then a DMA entry is pushed onto the DMA entry queue of the requester. An arbiter uses the TPS values to select DMA entries off the various queues for incorporation into a “snapshot”. The arbiter then selects DMA entries from the snapshot in an order for servicing such that memory access overhead in accessing the memory is reduced. Only after all DMA entries of the snapshot have been serviced is another snapshot of entries selected. Maximum latency in servicing a queue is controlled by assigning each queue a time out value (TOV). If a queue times out, then that queue is moved up in the order of servicing.
