Abstract: Acoustic activity detection is provided herein. Operations of a method can include receiving an acoustic signal at a micro-electromechanical system (MEMS) microphone. Based on portions of the acoustic signal being determined to exceed a threshold signal level, output pulses are generated. Further, the method can include extracting information representative of a frequency of the acoustic signal based on respective spacing between rising edges of the output pulses.

Abstract: Embodiments are directed to automated investigation of regression or other defects. A time-series of values for a metric associated with an execution of a verification action for a service may be provided. If a metric value in the time-series of values is outside of a control range, further actions may be performed, including: determining a last valid version of the service based on the time-series of values; determining a first invalid version of the service based on the time-series of values; determining changes associated with differences between the last valid version of the service and the first invalid version of the service based on the time-series of values; determining responsible users based on the determined changes; and generating a defect report based on the changes and the metric value that is outside of the control range such that the responsible users are associated with the defect report.

Abstract: Beverage cartridges, and methods of assembly, are disclosed that include a housing, a filter extending across an interior of the housing dividing the housing into an upper portion and a lower portion, a beverage ingredient disposed within the upper portion of the housing, and a supplement ingredient disposed within the lower portion of the housing. With this configuration, beverage cartridges as provided herein can be used to prepare a mixed beverage containing the beverage ingredient as well as the supplement ingredient.

Abstract: Systems and approaches for roasting coffee beans are described whereby a roasting apparatus is provided that includes a container and a heat source. The roasting apparatus is heated to a first temperature. Coffee beans are placed in the container, and at least one variable is measured while the coffee beans are in the container. Upon the at least one variable reaching at least one threshold value, a first quantity of a high-fat solution is added to the container, thereby coming into contact with the coffee beans. In some examples, the high-fat solution may be in the form of a clarified butter, and in particular, ghee butter. The coffee beans are then removed from the heat source to cool.

Abstract: A system for controlling the engagement and disengagement of a viscous type coupling is accomplished by controlling the relative positioning of a spring loaded valve arm relative to a fluid port through the use of an electrically-activated, temperature-sensitive member, such as a NiTi wire. The characteristics of shape memory alloy materials are such that they are hard above a predetermined temperature, but soft and ductile below a predetermined temperature. When engagement or disengagement of the coupling is desired, electrical current is introduced through the member, therein heating it above a predetermined temperature to harden it. This hardening causes the valve arm to either move to either cover or uncover a fluid port, depending upon the design arrangement of the valve arm relative to the fluid port. A controller coupled to a plurality of engine operating sensors and a power source controls the electrical activation as a function of a desired operating condition.

Abstract: An elevator cab includes primary and auxiliary light sources. A light sensor responsive to light from the primary light source causes activation of the auxiliary light source when the primary light source fails. The light sources are inside the cab for passenger use and/or outside the cab for maintenance worker use. A battery for auxiliary light is selectively charged by first and second current levels in response to the battery voltage being above or below first or second different thresholds.

Abstract: A method of controlling a fluid actuated fan drive system (12) for an engine (14) includes determining an engine speed. The speed of a fluid actuated engine-cooling fan (16) is limited when the engine speed is greater than or equal to an engine over-speed level. The fluid controlled fan drive system (12) includes a sensor (31) that generates an engine speed signal. The system (12) also includes the fluid actuated engine-cooling fan (16) and an engagement circuit (36) that is coupled thereto. A controller (28) is coupled to the sensor (31) and the engagement circuit (36) and limits operating speed of the engine-cooling fan (16) to less than a predetermined level when the engine speed signal is indicative of an engine over-speed condition.

Abstract: A method for determining the presence and/or absence of automobile insurance on State registered vehicles utilizes registered vehicle records and insurance record databases as provided by the State and private sectors. The records contain information indicating the presence of insurance on particular vehicles. A computer controlled by a computer software program compares preselected data fields in each vehicle record with corresponding data in the insurance records. Similar data field comparison(s) is (are) made between the records of the insurance database and the vehicle database. Records lacking matching data are moved to an exceptions database for further verification and handling. Vehicle records not having a matching insurance record are checked on a weekly basis to determine if a corresponding insurance record has been entered subsequently into the insurance database. Vehicle records lacking insurance records are indicative of no vehicle insurance and are delivered to authorities for further actions.
