A method according to an aspect of the present invention includes determining a phase offset by simultaneously providing a calibration signal to a first element of an antenna and a second element of the antenna opposite the first element. The method further includes receiving an intermix signal by a third element of the antenna, measuring an amplitude characteristic for the intermix signal, and determining a phase offset based on the amplitude characteristic. The phase offset can be used to adjust a signal provided to the first element so that signals transmitted from the first element and second element are in phase with each other. This method can account for phase errors due to the construction or design of the antenna, and allows antenna elements to be calibrated without the need for phase detector devices.

A compact, high power, power conversion apparatus including a rotor and a stator. The rotor includes a cylindrical casing, and a predetermined number of permanent magnets disposed on the casing, and is adapted for rotation about the axis of the casing. The stator includes a core and a plurality of sets of conductive windings, each set including a predetermined number of individual conductive windings and associated with an electrical phase. A respective collecting conductor is associated with each set of conductive windings, with each individual conductive winding of the set being electrically connected to the associated collecting conductor. The respective collecting conductors are disposed in a coolant flow path a coolant flow path directing coolant into contact with the stator windings, electrically isolated from each other and spaced apart from each other and from the windings. Collecting conductors in the form of continuous rings and in the form of a plurality of arcs are disclosed.

A method is described for controlling customer installations of software or data by providing to the customer an encrypted list of authorized installation targets, whereby the installation program reads and decrypts the list, and only allows installation to proceed if the customer's installation target has a serial number that matches one of the vendor-provided serial numbers in the authorization list. Provision is also made for allowing customers to add serial numbers to the list, within constraints predetermined by the software vendor. Also provided is a method for a customer to perform a predetermined number of installations, whereby the software maintains and decrements a counter in an encrypted file on a storage medium, keeping track of how many remaining installations a customer may perform.

Embodiments of the present invention provide methods, computer programs, and apparatus for adjusting a speed target of an aircraft. In particular, the adjustment of the speed target of the aircraft may allow that aircraft to maintain merging and spacing constraints with respect to a leading aircraft. According to one embodiment of the present invention, the speed target of an aircraft may be adjusted by obtaining a speed target, obtaining own ship track data for the aircraft, obtaining lead ship track data for a leading aircraft, and calculating a speed target adjustment based on the speed target, the own ship track data, the lead ship track data and merging and spacing constraints.

An entertainment center includes a base that expands horizontally to accommodate different width home theater displays; and, a light bridge that rests on top of one or more cabinets placed on either side of the base. The side cabinets provide a vertical column of open space for accommodating wiring among the entertainment system components and ventilation for heat generated by those components. The base includes casters to facilitate moving the base in and out from between the side cabinets. Sliding portions of the base extend horizontally yet continue to transfer all load weight onto the casters. The front woodwork of the base presents a pleasing seamless appearance as a consequence of overlapping trim pieces.

A method of producing a microelectronic device resistant to tampering, inspection and damage from surrounding environment or operating conditions includes: (i) applying an adhesion layer on a circuit including a die fixed and electrically connected to a laminate substrate; (ii) spraying, through a flame spray process, a tamper resistant coating over the applied adhesion layer; (iii) applying a first encapsulant for filling spaces and air pockets; (iv) removing air and gases from the first encapsulant; and (v) applying a second encapsulant around the first encapsulant for providing a moisture barrier 42 and handling surfaces for the microelectronic device.

A multiplexer, such as a diplexer, is delineated. The multiplexer may be employed in a communications system that may communicate in multiple frequency bands within a predefined range of frequencies, e.g., 2400 MHz-4900 MHz. The communications system may operate in a network, such as a wireless local area network, without significant interference from signals used by a cellular/mobile telephone system. The multiplexer may include multiple channels with bandpass filters that may be formed with lumped inductors and lumped capacitors. In at least one of the channels, the bandpass filter may be formed by combining at least one lowpass filter with at least one highpass filter.

Furniture systems are delineated including a first cabinet, a second cabinet and a base for supporting a provided object between the first cabinet and the second cabinet. One or both of the first cabinet and the second cabinet defines a space for which, in a first configuration of the system, the base resides outside of the space, and in a second configuration of the system, the base resides at least partially within the space. Accordingly, the delineated furniture systems can accommodate supporting on the base objects of various dimensions.

Disclosed are couplings for use in devices positioned in a molten metal bath. One is a rigid coupling that may include a counterweight, the coupling to reduce nonconcentric movements during rotation of a shaft, particularly a rotor shaft. Another coupling uses magnetic force, rather than a direct physical connection, to form a driving connection between a drive shaft (such as a motor drive shaft) and a driven shaft (such as a rotor shaft). In the event the rotor is jammed, the increased torque creates an overload that disconnects the drive shaft from the driven shaft in order to help prevent damage to the rotor, driven shaft, drive shaft and other components. Also disclosed is a coupling to transfer gas into a shaft, the coupling having a non-threaded internal surface to help prevent gas leakage and thus assist in preventing any resulting damage to the coupling and shaft.

Users of a simulator gain skills for investing using a simulator. The simulator simulates a business system that conducts a market transaction. The simulator selects a set of factors from a plurality of sets; selects a current factor from the selected set; and determines a price in accordance with the current factor. The simulator further updates a financial position of the user of the simulator in response to a transaction; and performs the transaction in accordance with the price and an input from the user. The input from the user corresponds in content to an input to the business system. Consequently, the user develops skill in specifying market transactions to be conducted by reviewing changes in the user's financial position. The simulator may include a simulated competitor having a financial position affected by transactions according to a strategy of the competitor selected from a set of stored strategies.
