Abstract: A loading system is constructed to load a hauling machine by a loading machine. The system includes a fiducial marker affixed to the hauling machine. A set of sensors of diverse sensory modalities is deployed on the loading machine that generate respective signals indicative of the fiducial marker in the corresponding sensor modalities. A processor on the loading machine determines a machine orientation in space of the hauling machine through machine perception applied to the signals. Loading the hauling machine by the loading machine is guided according to the machine orientation.

Abstract: A stakeout system is constructed to stakeout a worksite according to a site plan. The system includes a set of fiducial markers, each being associated with a corresponding construction operation performed at the worksite. A set of sensors having diverse sensory modalities generate respective signals from which information associated with the construction operation is conveyed. A processor is constructed to ascertain from the signals a location of a work machine at the worksite, as well as the corresponding construction operation performed thereat. The work machine is guided in performing the construction operation according to the location of the work machine in the site plan.

In an embodiment, wherein the fastening portion comprises at least one fastening means, which can be hook and loop straps. In an embodiment, the fastening portion is provided along at least a section of the cover portion periphery. The cover further comprises a cushioning means disposed on the cover portion, wherein the cushioning means is made of at least one of foam and rubber.

Abstract: A method of determining the real time state of a machine includes receiving acceleration and angular rate of motion measurements from IMU's mounted on components of a machine. Fusing signals received from the IMU's with separate Kalman filter modules by combining an acceleration measurement and an angular rate of motion measurement from each IMU to estimate an output joint angle for the component on which the IMU is mounted. Estimated and measured values of the output joint angle for each component are combined, a kinematic equation is solved to determine a real time value for at least one of position, velocity, and acceleration of the component at successive timesteps, and the determined real time values are applied to control movement of each component.

Abstract: A method of determining the real time state of a machine includes receiving, with at least one processor, from each of a plurality of Inertial Measurement Units (IMU's) mounted on different components of the machine, a time series of signals indicative of acceleration and angular rate of motion measurements for each of the components of the machine on which one or more of the plurality of IMU's are mounted. For each one of the IMU's on a separate component of the machine, the signals received from the IMU are fused with a separate Kalman filter module by combining an acceleration measurement and an angular rate of motion measurement from the IMU to estimate an output joint angle for the component of the machine on which the IMU is mounted.

Abstract: A firefighter multi-tool, comprising a head assembly having at least one interchangeable tool head with locking means, a first handle assembly, and a second handle assembly. The first and second handle assemblies house spring-loaded tools within. The at least one interchangeable tool head comprises spring-loaded trauma shears, a bridging head, channel-lock pliers, traditional pliers, an adjustable wrench, needle-nose pliers, a ratchet, and tin snips. A carrying case carries the head assembly having at least one interchangeable tool head with locking means, the first handle assembly, and the second handle assembly. The carrying case comprises a first compartment having a locking mechanism. At least a second compartment mounts upon the first compartment to house the at least one interchangeable tool head.

Abstract: An electronic package for an electronic device includes a substrate. A power transistor die has a lower surface and a upper surface, and the lower surface of the power transistor die is mounted on the substrate. A control circuit for controlling the power transistor is mounted to the upper surface of the power transistor die using an insulating epoxy.

Abstract: A power converter includes a plurality of switching stages, each switching stage including a series coupled pair of MOS-gated switching elements coupled together at a common node, each switching stage being connectable from a voltage source to a ground potential; a plurality of inductors coupled, at respective first ends, to the respective common nodes of the switching stages; and a shunt capacitor coupled from second ends of the plurality of inductors to the ground potential.

Abstract: An isolated forward switching power converter includes a primary side circuit and a secondary side circuit having an output inductor, a first MOS gated transistor coupled in series with the output inductor, a second MOS gated transistor coupled in shunt relationship with the output inductor, and a synchronous rectifier control circuit which senses the voltage across the output inductor and alternately biases the first and second transistors on and off in response thereto.

Abstract: A system is provided for automatically actuating an alarm whenever a would-be thief attempts to remove the antenna from a vehicle equipped with a C.B. radio or other communication system. The preferred embodiment includes a hidden switch which remains depressed by the antenna until it is partially unscrewed, at which time the switch closes the alarm circuit. For example, the horn of the vehicle may be connected to the switch and serve as the alarm.
