    摘要: A grinding wheel is used to pulverize solid test samples and propel particles thereof into a flame for analysis by an instrument such as a mass spectrometer. The sample is attached to one end of a pivoted lever arm. The other end of the lever arm is connected to a solenoid. Activation of the solenoid brings the sample into contact with the rotating grinding wheel. The solid particles produced by the wheel are propelled into the flame through a slot in an intermediate draft shield. The sampling cone of a conventional mass spectrometer or similar instrument may be placed in the flame to analyze the nature of the test materials. The device may also be used to inject test particles into the air or gas feed stream ahead of the flame if desired.

    摘要: The Back-up Panorama Camera is a unique back up camera with three cameras mounted on a license plate frame and a power hinge to swing the license plate out behind the vehicle. What is new about this invention is that it utilizes the license plate in order to get a better view behind the car. It also uses three cameras in close proximity to each other in order to see absolutely everything behind the car. This will help drivers avoid accidents in busy parking lots and keep pedestrians safe.

    摘要: A tamper sensing circuit is provided for an electrical device wherein an enclosure may be opened to access data by a user that does not possess the ability to achieve normal access by satisfying data security measures such as use of a password. A screw used to secure enclosure halves together is connected by a conductive coating at the enclosure member surface into which the screw is threaded to connect a tamper sensing circuit to the device ground potential. A tamper sensing circuit output node is maintained at the circuit ground potential as long as the screw is in electrical contact with the enclosure conductive coating. When the screw is disengaged from the enclosure member threaded opening, the output node is no longer grounded and rises to a supplied electrical potential indicating tampering and enabling appropriate corrective action. The conductive coating on the enclosure member which connects the screw to circuit ground may be applied or may already be present to suppress electromagnetic interference.

    摘要: A shoulder strap for carrying a notebook computer is formed as an elongated member with a locking mechanism at a first end which attaches to the lock slot of the computer and a loop at the opposite end. By passing the strap through the loop, the opposite end portion of the strap is positioned around the computer adjacent the side opposite the side which includes the lock slot. With the first end of the strap secured to the computer by securing the locking mechanism at the computer lock slot, the intermediate portion of the strap extends over the users shoulder to enable transport of the computer. By forming the strap using a plastic coated steel cable, the shoulder strap may be used for both carrying the computer and as a security cable for securing the computer when unattended. The shoulder strap surfaces that engage the user's shoulder and surround and engage the notebook computer are formed of non-adhesive, non-slip material. In an alternate embodiment, to more positively secure the strap portion surrounding the computer, hook and loop tape is applied to both the strap portion engaging the computer and the computer side over which the assembled strap passes, so that the strap can be prevented from slipping off the computer when assembled for transport.

    摘要: A circuit for providing a follow-on current between the electrodes of a traveling spark ignitor after an initial break down between the electrodes has occurred is disclosed. The circuit may include first and second portions which, respectively, provide first and second voltages to the ignitor. The first portion may be a conventional ignition circuit. The second portion provides the follow-on current. The second portion may provide the follow-on current as a single discharge or as a multi-stage discharge.
