Abstract: A miniaturized turbogenerator (200) to directly provide electrical propulsion (307 308, 309) to small land, air, and maritime vehicles without an intervening electricity storage battery (315). The invention comprises of a process of miniaturization (500) of a turbine engine core (100), in particular its compressors and turbines (400), by means of hyper-feed machining by linear force alone, i.e. without rotation of either the workpiece or the cutting tool (505), and a resulting apparatus of a miniaturized turbogenerator (200) that has sufficient power density to provide high-performance electrical propulsion (310) for commercially feasible automobiles, urban air mobility vehicles, and other small vehicles and vessels with greater performance than battery-electric vehicles (300).

Abstract: An electromagnetic clutch (1) of an air conditioning compressor (2), in particular for a motor vehicle (11), transmits a torque to a drive shaft (3) of the compressor (2) depending on an electric current (I) being fed to clutch coils (4) of the electromagnetic clutch (1) to generate an electromagnetic clutch force. According to a control method (10), a slippage of the electromagnetic clutch (1) is determined by a difference between the rpms of the electromagnetic clutch (1) and of the drive shaft (3), and is monitored by a slippage sensor (5). The electric current (I) and the resulting clutch force are adjusted dependent on slippage by a pulse width modulation controller (6) of the compressor (2). The pulse width modulation controller (6) is electrically connected to the clutch coils (4) and modulates a pulse width of the electric current (I) fed to the clutch coils (4).

Abstract: A system for auditing and analyzing work performed by other individuals is disclosed. Data is imported into the system, where the data represents one or more elements of work performed at one or more locations. This data is parsed out into individual items to be audited. These items, along with a number of questions with discrete answers are then transmitted by the system to one or more auditing technicians who audit the work performed by capturing one or more visual images. These visual images, along with answers to the questions are then transmitted back to the system. The system then saves the visual images and associated answers for archiving and generating reports.

Abstract: A system, method and program adapted for collecting images of job-site conditions, plans and specifications. Images are annotated with attributes that relate to the location, time and trades involved and other aspects of the images. Job site images are collected with a camera connected to a portable data collection device. The portable data collection device is programmed with image attributes for a particular project. Images are also annotated with attributes gathered by sensors, such as GPS position data and direction information. Images with attached attributes are uploaded to a database server and indexed into a relational database. Images can be flagged and determined to be images for review which triggers automatic notification to the involved parties and follow up to confirm resolution. Authorized participants can access images in near real time, to make funding, insurance and other judgments about the project. Images are archived for safekeeping and long-term storage.
