Abstract: A load control system for controlling the amount of power delivered from an AC power source to a plurality of electrical load includes a plurality of independent units responsive to a broadcast controller. Each independent unit includes at least one commander and at least one energy controller for controlling at least one of the electrical loads in response to a control signal received from the commander. The independent units are configured and operate independent of each other. The broadcast controller transmits wireless signals to the energy controllers of the independent units. The energy controllers do not respond to control signals received from the commanders of other independent units, but the energy controllers of both independent units respond to the wireless signals transmitted by broadcast controller. The energy controller may operate in different operating modes in response to the wireless signals transmitted by the broadcast controller.

Abstract: A connecting rod (1) has a small end (2) that is connectable rotatably to a piston, a connecting rod big end (3) that is connectable rotatably to a crankshaft, and a shank (4) between the ends (2, 3). The connecting rod big end (3) has a big end (5) and a connecting rod bearing cover (6) that can be screwed to the big end (5). Through bores (7) penetrate the cover (6) and threaded bores (8) penetrate the big end (5) in alignment with the through bores (7). Screws (9) penetrate the through bores (7) and screw into the threaded bores (8). A recess (10) is in the region of the respective threaded bore (8) on its side that faces away from the connecting rod bearing cover (6) and is directed toward the connecting rod big end (3) and is eccentric with respect to the thread axis (11).

Abstract: A refrigeration unit and diagnostic method therefore are provided. The refrigeration unit includes: a housing with an insulated cavity for storing food and beverages; a vapor cycle system operative to cool the food and beverages in the insulated cavity; a plurality of sensors in communication with the vapor cycle system and outputting data relative to the vapor cycle system; and a controller that, according to the data from the plurality of sensors, determines an occurrence of an event. Wherein the controller logs the data from the plurality of sensors to a data structure according to a first data-logging mode, and logs the data to the data structure according to a second data-logging mode upon occurrence of the event. In one embodiment the refrigeration unit may be a refrigeration line replaceable unit (LRU) configured for an aircraft galley.

Abstract: A switchable air intake system for a multicylinder internal combustion engine has at least one short and one long intake manifold whose cross sections are controllable by at least one regulating unit as a function of operating parameters (in particular the rotational speed of the internal combustion engine). The short intake manifold for a first cylinder bank row and the long intake manifold for a second cylinder bank row of the internal combustion engine, are controllable via a joint regulating unit (56, 58).

Abstract: The antenna combination has at least two individual antennas which form part of at least one resonant circuit which appears on an electrically conductive surface. The output signals of the individual antennas are combined, for example, added. The antennas are preferably located at the edges of the electrically conductive structure. The antenna combination of the invention is particularly suitable for transmitting and receiving in vehicles because antennas which have transmitting and receiving properties equivalent or superior to those of rod and disc antennas can be built into the vehicle. The antenna combination can be used advantageously in a diversity process.

Abstract: According to the receiving method for mobile reception has a plurality of individual receiving antennas, also known as diversity receiving method, on the individual antenna output signals an auxiliary modulation is superimposed and the antenna output signals are added to give a summation signal which as amplified selected intermediate-frequency summation signal is then demodulated in relation to amount and frequency or phase, the phase position of an individual signal in relation to the phase position of the summation signal and/or the amplitude contribution of an individual signal to the amplitude of the summation signal thereby being determined. This information is utilized for optimizing the useful signal with a view to optimum interference suppression for example in that the phases and/or amplitudes of the high-frequency individual signals are changed in dependence upon the phase position and/or amplitude contribution determined.
