Abstract: A method and apparatus for detecting, for wheel assemblies on opposite ends of an axle during an alignment angle measurement or inspection process, relative movement or slip between the alignment angle sensor or optical target and the wheel assembly upon which it is mounted. Changes in measurements of invariant characteristics of the solid axle or an associated wheel assembly are observed by an alignment measurement or inspection system as indications of movement or slip between at least one of the alignment angle sensors or optical targets and the associated wheel assembly. Upon detection of a change a measurement of an invariant characteristic, an operator is alerted by the alignment measurement or inspection system to the presence of movement or slip of one or both of the alignment angle sensors or optical targets associated with the wheel assemblies of the axle.

Abstract: A chemical-electromagnetic hybrid propeller with variable specific impulse. Fuel gas ejected out from a spraying tube of the chemical propeller through chemical propulsion enters an ionization chamber through a first magnetic mirror tube for ionization. The fuel gas after ionization is heated up by radio-frequency ion cyclotron waves in an ion cyclotron wave heating chamber so as to improve the kinetic energy. Then a second magnetic mirror tube is used, so that ions in the fuel gas after the ionization are heated up many times in a reciprocating manner between the magnetic mirror tubes, and ejected to generate forward propulsion force. By means of the propeller, the propulsion force and the specific impulse are greatly increased.

Abstract: Receive signals may be combined to form receive beam signals at multiple receive frequency channels. The receive beam signals may be partitioned by receive frequency channel into multiple groups of receive beam signals, each group corresponding to a different frequency spectrum and the multiple groups including a first group and a second group. The first and the second group of receive beam signals may be communicated to a first and a second switch, respectively. The first and the second group of receive beam signals may be switched by the first switch and the second switch, respectively, to generate a first and a second group of transmit beam signals. Transmit beam signals that include the first and the second group of transmit beam signals may be combined to form transmit signals to be transmitted using corresponding transmit antenna elements to form one or more transmit beams at multiple transmit frequency channels.

The method includes: blowing in a first-stage gas containing oxygen and recycled flue gas from the bottom of the furnace; blowing in a second-stage gas containing recycled flue gas from a transition zone between a dense-phase zone and a dilute-phase zone of the furnace; and blowing in a third-stage gas containing oxygen from a side wall of the furnace.

Abstract: Front bumper assemblies for vehicles are disclosed. The front bumper assemblies may include a bumper reinforcement with a plurality of pedestrian energy absorbers positioned adjacent to a front face of the bumper reinforcement. The plurality of pedestrian energy absorbers are arrayed along a width direction of the bumper reinforcement. A plurality of bumper cover supports are positioned at least one of atop or adjacent the bumper reinforcement and may be attached to the bumper reinforcement. Each of the plurality of bumper cover supports is offset from the forward contact surfaces of the pedestrian energy absorbers in a front impact direction.

Abstract: A smart safe include one or more note validators. Access to the note validators and internal workings of the smart safe is defined by an applicable level of security at the smart safe. The applicable level of security may be dependent on whether the smart safe is experiencing an error condition and/or the identification of a user trying to access the smart safe. By allowing some users limited access to the note validators, the users may be able to resolve some error conditions without compromising the integrity of notes stored within the smart safe and without relying on dedicated service personnel to resolve the error condition at the smart safe.

Abstract: A system and method for removing unwanted elements from a gas stream. A biogas stream may be combined with a water stream influent in a venturi device to produce a gas-water mixture effluent. The gas-water mixture effluent is processed in a degas separator to separate and produce a relatively low solubility gas effluent and a relatively high solubility gas-water mixture effluent. The relatively high solubility gas-water mixture effluent is processed through a discharge pressure control valve based on a selected pressure to be maintained in said degas separator and then discharged or reused.
