摘要： A differential RF input signal drives the plus and minus terminals of a center tapped primary winding, which couples the differential RF input signal to the plus and minus terminals of a center tapped secondary winding. From the secondary winding, the coupled, differential RF signal drives a double-balanced mixer core operating in response to a differential local oscillator signal. The output of the mixer core is a differential IF signal representative of the differential RF input signal down-converted at the local oscillator frequency. A step reduction in gain associated with the RF input signal may be implemented using bypass circuitry coupled across the primary of the transformer, wherein a relatively small resistance or impedance is coupled across the primary to effectively reduce the load of the differential amplifiers driving the primary.

摘要： An input amplifier stage couples its output power to a second gain stage through a transformer. The transformer coupling allows for the removal of a diode voltage drop at a second gain stage, thereby allowing the collector of the transistor in the second stage to have a larger voltage swing.

摘要： An optimistic, latch-free index traversal (“OLFIT”) concurrency control scheme is disclosed for an index structure for managing a database system. In each node of an index tree, the OLFIT scheme maintains a latch, a version number, and a link to the next node at the same level of the index tree. Index traversal involves consistent node read operations starting from the root. To ensure the consistency of node read operations without latching, every node update operation first obtains a latch and increments the version number after update of the node contents. Every node read operation begins with reading the version number into a register and ends with verifying if the current version number is consistent with the register-stored version number. If they are the same, the read operation is consistent. Otherwise, the node read is retried until the verification succeeds. The concurrency control scheme of the present invention is applicable to many index structures such as the B+-tree and the CSB+-tree.

摘要： Embodiments of the invention may provide for a long delay generator for the spectrum sensing of cognitive radio systems. The long delay generator may include an Analog-to-Digital Converter (ADC), memory element, and Digital-to-Analog Converter (DAC). The memory element may utilize shift register bank or Random-Access Memory (RAM) cells. The long delay generator may provide for a selectable delay by digitizing the received signal, delaying the received signal in the digital domain, and reconstructing the delayed signal as an analog. The analog delayed signal may then be compared or otherwise correlated with the original input signal using an analog auto-correlation technique to determine whether a meaningful signal type has been identified or otherwise detected.

摘要： A butane fuel supply container for a cooking stove, the container has a thin side wall held rigid by the vapor pressure of the fuel, but the side wall can be finger deformed when the can has been depressurized or hand crushed with the exit valve of the container open, the vapor therein being expelled as the container is deformed or crushed. The vapor tube has a vapor entrance in the vapor pocket above the pool of liquid fuel when the container is correctly oriented in the stove. The vapor tube passes vapor through a valve at the dome of the container.

摘要： The present invention provides an improved optical frequency demodulation technique for extracting overhead information from an optical channel signal carrying both high bit rate payload and low rate overhead data. The invention makes use of asymmetrical Mach-Zehnder interferometry (AMZI) in an optical frequency demodulator to efficiently extract the overhead information from the optical channel signal by frequency discrimination without necessitating a complete demodulation of the optical channel signal. By comparison to existing demodulation schemes, the invention provides an all-optical low cost, high gain technique for recovering the overhead data which improves the payload signal-to-noise ratio and enhance performance.
