摘要:
Voltage regulators and methods for regulating voltages are disclosed. A switching circuit with an energy-storage element and a plurality of switches may be used to produce a regulated voltage from an unregulated voltage source. A control circuit may be used to monitor both the energy stored in the energy-storage element and the regulated voltage, and operate the switches in cycles when the regulated voltage falls below a threshold voltage. Each cycle includes a first phase with the energy-storage element coupled to the unregulated voltage source, followed by a second phase with the energy-storage element coupled to the output of the voltage regulator, with the unregulated voltage source being coupled to the output of the voltage regulator during a portion of each of the cycles, and wherein the duration of the first and second phases of each of the cycles is a function of the energy stored in the energy-storage element.

A monitoring device monitors an apparatus that clinches together sheet metal panels. In particular, a die assembly positioned on one side of the panels has a button forming die cavity defined by an anvil at the bottom of the die cavity and a plurality of radially moveably die blades at the side of the cavity. A plunger is positioned on the other side of the panels and registers with the die assembly so that linear displacement of the plunger plastically deforms the panels axially into the die assembly to engage with the anvil and then further linear displacement of the plunger will then deform the panels radially outward as permitted by the outward radial movement of the moveable die blades. Transducers measure the linear displacement of the plunger, the radial outward displacement of the radially moveable die blades, and the magnitude of the axial force applied against the anvil.

A measurement tool for determining at least one of the loft angle or the lie angle of a golf club. The measurement tool includes a golf club head support structure having a mating surface and at least one beveled support element. The gauge also has a clamping tool capable securing the golf club head to the golf club head support structure. The clamping tool may include a pushing element and a mating element. The mating element has a jaw for applying a lateral force to the golf club head to secure it to the golf club support structure and a fastening plate for applying a vertical force to the golf club head to secure it to the golf club support structure. A gauge capable of indicating at least one of the loft angle or the lie angle of the golf club is positioned adjacent to the golf club head support structure.

A crash worthy vehicle partition for securely separating the front of a vehicle from the rear of vehicle. The vehicle partition includes upper mounting brackets and lower mounting brackets that allow for limited, rearward motion of the vehicle parrition in the event of a rear-end collision to reduce the crash impact forces on front seat occupants. The vehicle partition further includes pivotable wings that are disposed on each side of the vehicle partition in a vehicle's side curtain airbag deployment zones. These pivota+e wings are mechanically retracted out of the side curtain airbag; deployment zones in the event of an airbag deployment event.

An improved spot welding system for clamping and welding a plurality of workpieces at predetermined datum locations includes a clamping element, and at least one electrode. The preferred electrode(s) and element are concentrically alignable during engagement, and configured to produce an annular weld about the datum location. More preferably, the workpieces define an opening at the datum location, the element includes an insulated pin at least a portion of which is configured to pass-through the opening, and the electrode defines an inner space configured to receive the portion of the pin, when the electrode and element fully engage the workpieces.

A system, method and apparatus for resource reallocation based on ambient condition data is disclosed herein. The system includes a planning module (102) for configuring plan data to include a primary sequence and an auxiliary sequence, a rule table (116) for storing the auxiliary sequence, an ambient condition receiver (124) for receiving the ambient condition data, and a routing processor (126) for accessing the rule table (116) to allocate an auxiliary sequence in place of a primary sequence in the event that particular ambient data is received.
摘要:
A pneumatic raisin harvester for harvesting dried-on-the-vine raisins grown on a trellis system comprising a plurality of support stakes and a trellis wire interconnecting the stakes spaced apart from the vine trunk. The harvester has a support assembly attached to and transported by a tractor or other vehicle. A support arm extends outwardly from the tractor to support a harvesting head having a head enclosure configured to straddle the trellis wire and support stakes. A crop separating mechanism, such as a plurality of beater rods, disposed inside the head enclosure dislodges raisins from the vines. A raisin collecting system transports the raisins to a venturi inlet that is hydraulically connected to a hydraulically powered pneumatic conveying system comprising a blower that discharges pressurized air through one or more air tubes so as to deposit the raisins in one or more raisin bins on a bin trailer towed by the tractor.
