Abstract: Devices and systems for determining an alternator condition in a motor vehicle are provided. The method includes performing a plurality of micro wakeups to capture voltage values during a cranking event, determining the maximum cranking voltage and its timestamp, detecting an ignition signal, determining the maximum device voltage and its timestamp, and determining a potential alternator undercharging condition if a duration between the maximum cranking voltage timestamp and the maximum device voltage timestamp is greater than an undercharging indicator duration threshold. Advantageously, an alternator may be repaired or replaced before it fails thus averting having the motor vehicles inoperable.

Abstract: Described implementations provide a level for measuring a level of a target surface. The level has a base structure having a bottom surface, a top surface, a rear surface, and a front surface, and a bubble level disposed on the top surface of the base structure. The bottom surface is disposed at (1) a desired slope angle of the target surface along a first axis, and (2) a predetermined pitch angle along a second axis of the base structure, the second axis perpendicular to the first axis. The bubble level is disposed on the top surface along the first axis to indicate a slope level of the target surface relative to the predetermined slope angle and along the second axis to indicate a pitch level of the target surface relative to the predetermined pitch angle. The base structure has a ledge extending in an engagement direction along a third axis.

Abstract: A chair includes a seating portion connected to a back portion and a hanger connected to the back portion. The hanger includes a front plate, a back plate opposing the front plate, and a plate separator defining a lower and an upper gap between the front plate and the back plate. An interior surface of the front plate that at least partially defines the lower gap includes a first concave radius of curvature opening away from the back plate and a sidewall portion angled towards the back plate. An interior surface of the plate separator that at least partially defines the lower gap includes a second concave radius of curvature opening away from the back plate and a sidewall portion angled towards the back plate.

Abstract: A chair hanger system includes a front plate, a back plate opposing the front plate, a plate separator defining a gap between the front plate and the back plate, and a first and second hook attached to the back plate. The first hook defines a first opening geometry and the second hook defines a second opening geometry. A set of spacer blocks includes a first spacer block configured to insert within the first opening to reduce and change the first opening geometry, and a second spacer block configured to insert within the second opening to reduce and change the second opening geometry. A chair hanger device is also described.

Abstract: The disclosure features methods and systems that include directing an ion beam to a region of a sample to liberate charged particles from the region of the sample, where the directed ion beam is pulsed at a first repetition rate, deflecting a first subset of the liberated charged particles from a first path to a second path different from the first path in response to a gate signal synchronized with the repetition rate of the pulsed ion beam, and detecting the first subset of the liberated charged particles in a time-of-flight (TOF) mass spectrometer to determine information about the sample, where the gate signal sets a common reference time for the TOF mass spectrometer for the first subset of charged particles liberated by each pulse of the ion beam.

Abstract: The disclosure features systems and methods that include: exposing a biological sample to an ion beam that is incident on the sample at a first angle to a plane of the sample by translating a position of the ion beam on the sample in a first direction relative to a projection of a direction of incidence of the ion beam on the sample; after each translation of the ion beam in the first direction, adjusting a focal length of an ion source that generates the ion beam; and measuring and analyzing secondary ions generated from the sample by the ion beam after adjustment of the focal length to determine mass spectral information for the sample, where the sample is labeled with one or more mass tags and the mass spectral information includes populations of the mass tags at locations of the sample.

Abstract: Mechanisms are provided to implement an intraoral control mechanism that allows a user to control an operation of a computer system or an electronic device. The intraoral control mechanism detects a strain based on a tongue of a user moving a control mechanism away from a fixed position; transduces the detected strain into a control signal; amplifies an amplitude of the control signal thereby producing an amplified control signal; converts the amplified control signal to a digital input signal; modulates the digital input signal onto a transmission frequency wave; and transmits the digital input signal to the computer system. The computer system may then either execute the digital control signal on the computer system itself to perform an operation or transmit the digital control signal to the electronic device so as to operate as indicated by the digital control signal. The digital input signal is saved for characterization of the user.
