Abstract: Heat resistant sensors equipped with any of a variety of transducers for measuring any of a variety of properties of fluids are constructed with components comprising materials that can withstand very high temperatures. Some embodiments of the sensors include a first pressure sensitive element and a second pressure sensitive element with respective first and second membranes positioned in juxtaposed relation to each other to form a capacitor. Some embodiments include a pusher that extends from the membrane toward a first electrode. Some embodiments have a housing comprising a ceramic substrate with a sensor element mounted on an inside surface of the substrate. Other embodiments have direction sensing capabilities including a heater positioned in a core material and at least three temperature sensors located at or near the peripheral surface of the core material and spaced apart angularly in relation to each other.

Abstract: A method evaluates whether a web domain is malicious. The method forms a feature vector, including data from web crawling. The features may include: whether the domain is cached from web crawling; the number of unique publicly accessible URIs hosted on the domain; the number of backlinks referencing the domain; the number of unique domain names in referring backlinks; the number of unique IP addresses in the referring backlinks; the number of unique IP address groups in the referring backlinks; and the proportion of hyperlinks to the domain from popular websites. For multiple classifiers, the method computes a probability that the domain is malicious. Each classifier is a decision tree constructed according to a subset of features and a subset of sample feature vectors. The method combines the individual probabilities to form an overall probability and returns the computed overall probability to the client.

Abstract: A salt of the formula: Mg[Al(R)4]2, where R represents a halogen-free compound selected from a deprotonated alcohol or thiol; or an amine; or a mixture thereof.

Abstract: A portable device for detecting an analyte associated with a target organic molecule in a liquid and/or solid substance. The device includes a test chamber, a probe, and a sensor. The test chamber contains a liquid volume of test solution including an analytical reagent selected to react with the analyte. The test chamber is sealed by a pierceable membrane wall. The probe is removably positionable to pierce the membrane wall to deposit a sample in the test chamber to form a test mixture with the test solution. The sensor is positioned to detect one or more characteristics of the test mixture in the test chamber indicative of a reaction between the analyte and the analytical reagent.

Abstract: A method of making a salt of the formula: Mg[Al(R)4]2, where R represents a compound selected from a de-protonated alcohol or thiol; an amine; or a mixture thereof. The method comprising the steps of; combining a Mg(AlH4)2 precursor with an alcohol, thiol or amine of the general formula R—H to create a reaction liquor containing Mg[Al(R)4]2; and washing the reaction liquor in an organic solvent.

Abstract: There is disclosed inhaler testing apparatus, in which at least one flow regulation valve, such as a needle valve, is located within a conduit. The flow regulation valve divides the conduit into inlet and outlet sides of the valve. The inlet side is arranged for connection to an inhaler and the outlet side for connection to a vacuum source. An electric motor provides variable adjustment of a flow opening through the valve. At least one sensor senses pressure or flow rate in the inlet side and a controller automatically adjusts the flow opening through the valve in response to readings from the at least one sensor. The apparatus may also comprise a shut off valve, such as a solenoid valve.

Abstract: Techniques are described that relate to various aspects of converting the mechanical energy of instrument strings to digital representations for use in a variety of applications.

Abstract: A system and method for providing a voice communication service between a first user and a second user after the first user and the second user are communicating via a non-voice communication service is described. The non-voice communication service may be processed through a server in communication with the first and second users. The non-voice communication service is monitored for a voice service request, and upon receipt of the voice service request, establishment of a voice communication service is initiated between the first and second users through the server. The first and second users may be anonymous to each other over the non-voice communication service and the voice communication service.

Abstract: A refuse truck has a container for receiving refuse, and a packer panel for compacting refuse. The forces for compacting refuse are provided by hydraulic cylinders. The hydraulic cylinders extend through and are coupled to the packer panel. The hydraulic cylinders are telescopic or rod cylinders that have an open length several times their closed length. The hydraulic cylinders provide bi-directional forces so that the packer panel can be pushed away from or pulled towards the front wall of the container.
