Abstract: A ruggedized adjustable mounting system is described for adjustably coupling and selectively locking a component supported in a fixture of the mount in a desired orientation. In some embodiments, the mounting system includes one or more kinematic couplings that support a fixture on a base and one or more adjustable couplings that are configured to adjust a separation distance between two opposing portions of the fixture and the base to selectively pivot the fixture about one or more axes of rotation.

Abstract: A computer-implemented method for efficiently estimating the number of unique elements in a collection of elements comprises generating, via hash logic, hash values associated with the elements. The hash values specify bit positions within an array of bits. Hash values output from the hash logic conform to a geometric distribution such that bit positions of the array of bits corresponding to lower orders bits are more likely to be generated than bit positions corresponding to higher-order bits. Bits of the array of bits corresponding to the bit positions are set. The number of bits of the array of bits that are set is counted. Estimation logic estimates the number of unique elements of the collection of elements as a function of the number of bits of the array of bits that are set.

Abstract: A computer-implemented method for efficiently estimating the number of unique elements in a collection of elements comprises generating, via hash logic, hash values for each element of the collection of elements. The method further comprises specifying, in a sketch-frequency table, a set of discrete statistical values associated with the hash values and, for each discrete statistical value of the set of discrete statistical values, information indicative of a frequency at which binary representations of the hash values are associated with the discrete statistical value. The cardinality of the collection of elements is estimated based on the sketch-frequency table.

Abstract: A vehicle includes an engine, a transmission, and a controller. The engine is configured to generate power to propel the vehicle. The transmission has gears and clutches configured to shift between the gears. The controller is programmed to operate the clutches during wide-open throttle events to upshift the gears at shift points corresponding to engine speeds. The controller is further programmed to adapt the shift points by increasing the shift points over a series of the wide-open throttle events from initial values to mature values.

Abstract: A reverse osmosis system to be connected to a feed water conduit and producing permeate water is disclosed. The reverse osmosis system includes a plurality of tubular bodies each having a first end and a second end, a first inner end plate attached to the first end of the tubular bodies, and a second inner end plate attached to the second end of the tubular bodies. The plurality of tubular bodies houses a filter, a pump, and two reverse osmosis membranes therein. The plurality of tubular bodies is configured to be connected in in fluid communication with each other via channels disposed within the end plates.

Abstract: A vehicle includes a powertrain, an inertial measurement unit configured to measure inertial forces exerted onto the vehicle, and a controller. The controller is programmed to control the torque at the powertrain based on a mapped relationship between the inertial forces and a vehicle velocity, wherein the mapped relationship utilizes at least one mapping parameter. The controller is further programmed to estimate a mass of the vehicle based on the mapping parameter.

Abstract: A vehicle transmission includes a plurality of friction clutches and a selectable one-way clutch. The transmission also includes a controller programmed to, in response to detecting a component fault, switch the selectable one-way clutch from a passive state to an active state by commanding engagement of a first subset of the friction clutches to establish a slip elimination state. The controller is also programmed to, following establishment of the slip elimination state, command the selectable one-way clutch to the active state.

Abstract: Ideally, when a transmission is in Neutral, no torque should be exerted on the vehicle wheels by the powertrain. However, even with all clutches in a gearbox disengaged, some torque may be transmitted from a turbine shaft to the transmission output due to clutch drag and transmission component inertia. To avoid transmitting torque, a subset of clutches may be engaged to produce an input tie-up state, this holding the turbine shaft against rotation while permitting rotation of the output element.

Abstract: A transmission includes a selectable one-way clutch with active and passive states. Successful transition from the active state to the passive state is only possible when there is no torque tending to cause overrunning. After commanding a transition from the active state to the passive state, a controller partially engages a first friction clutch to induce a torque tending away from overrunning until a lash crossing is detected. Then, the controller releases the first clutch and partially applies a second clutch to induce a torque toward overrunning. When slip is detected, indicating successful achievement of the passive state, the second clutch is released.

Abstract: A transmission includes a selectable one-way clutch with an active state and a passive state. To avoid occupant discomfort and hardware damage, transitions from the passive state to the active state must only be commanded when no or very little slip is present across the selectable one-way clutch. Several methods are presented to eliminate slip, depending on vehicle speed. When the vehicle is stationary, full engagement of a clutch that causes slip to be proportional to vehicle speed eliminates slip. When the vehicle is moving backwards, partial engagement of the above clutch eliminates slip. When the vehicle is moving forwards, full engagement of all but one clutch of a tie-up condition and partial engagement of the remaining clutch of the tie-up condition brings the vehicle to a stop and eliminates slip.

Abstract: A system and associated method is disclosed to monitor physiological activity of a subject. One or more sensors are positioned in or on a support, the support being adapted to receive the subject, at least a first one of the sensors being adapted to produce a first signal indicative of movement of the subject over time. Processing apparatus is adapted to identify first, second and third portions of the first signal. The first and third portions correspond to first and third time periods, respectively, during which the subject changes body position on the support. The second portion corresponds to a second time period, between the first and third time periods, during which substantially no change in body position of the subject on the support takes place.

Abstract: A magazine for a high capacity loader for sequentially loading a plurality of projectiles into a launcher. The magazine has a magazine housing for holding a plurality of projectiles. The magazine housing has an opening providing access to a projectile chimney. The projectiles exit the magazine through the opening in the magazine housing via the projectile chimney. An aperture is provided in a sidewall of the projectile chimney and the aperture leads to a piston chamber. A pneumatically actuated actuator is provided in the piston chamber. The pneumatically actuated actuator drives an indexing assembly for the launcher.
