摘要:
A coated ceramic cutting insert for removing material from a workpiece, as well as a method for making the same, that includes a ceramic substrate with a rake surface and at least one flank surface wherein a cutting edge is at the juncture therebetween. A wear-resistant coating scheme that includes an alumina-containing base coating layer region, which has at least one exposed alumina coating layer, deposited by chemical vapor deposition on the substantially all of the surfaces of the ceramic substrate that experience wear during removal of material from the workpiece. The exposed alumina coating layer exhibits a blasted stress condition ranging between about 50 MPa (tensile stress) and about −2 GPa (compressive) as measured by XRD using the Psi tilt method and the (024) reflection of alumina. The exposed alumina coating layer is the result of wet blasting a titanium-containing outer coating layer region from the surface of the alumina-containing base coating layer region.

A multipath detector includes an RF module receiving multiple signals, and a correlator module receiving the signals from the RF module. The correlator module correlates the signals to create a composite ACF, and produces samples of the composite autocorrelation function (ACF). The samples are time delayed relative to each other. The multipath detector also includes a carrier phase processor that receives the samples and estimates carrier phases associated with each of the samples. The carrier phase processor employs the estimated carrier phases to determine if one of the signals is subject to a multipath delay.

Methods and apparatuses are provided for use with mode switchable navigation radios and the like. The methods and apparatuses may be implemented to selectively switch between certain operating modes based, at least in part, a mode-switching test that takes into consideration one or more non-timed test conditions to determine if mode-switching may be enabled.

A position location system, method, and apparatus are disclosed. A wireless device receives a first signal and obtains an identifier indicative of a first location from the first signal. The first signal can be received from a cellular base station and the first identifier can be a mobile country code. The wireless device uses the identifier to determine the availability of signals from a regional satellite system at the first location. If signals from the regional satellite system are available at the first location, the wireless device retrieves information associated with one or more satellite vehicles in the regional satellite system. The information can include pseudo-random number codes and a Doppler search range corresponding to the first location. The wireless device receives a second signal and processes the second signal to obtain first satellite signal information. The wireless device determines its position at least partially based on the first satellite signal information.

摘要:
A method for decreasing nicotine and other substance use in humans is disclosed. Tetrahydroberberine (THB) and its analogs, l-Tetrahydropalmatine (l-THP) and l-Stepholidine (l-SPD), are present in and can be isolated from several plants in the Magnoliidae superorder. According to the disclosed method, THB and its analogs are used to block nicotine-induced DA release, and modulate heterologous or homoeric expression of human nicotinic acetylcholine receptors (nAChR) in humans. Specifically, THB exhibits bi-directory modulation of α4β2-nAChR-mediated currents induced by nicotine. THB also shows predominant inhibition on homologously expressed α7-nAChR function. Thus, according to the disclosed method, THB is used to simultaneous blockade midbrain DA system function, the brain reward center, and neuronal α4β2- and α7-nAChR function, the major nicotine targets in the brain. Therefore, THB and its analogs serve as a novel class of natural compounds to decrease nicotine dependence in humans. Furthermore other substances, such as alcohol, cocaine, and opiates, also operate by triggering the brain reward center, resulting in a cycle of substance or alcohol abuse. THB and its analogs can be used to decrease use of substances such as alcohol, cocaine, and opiates. Finally, because THB and its analogs are DA antagonists, THB and its analogs can also be used as a treatment for Parkinson's Disease, Alzheimer's Disease and Schizophrenia.
摘要:
A regulator for regulating the output from a high-voltage pump, Vpump, to provide a regulated load voltage, Vpp, to a load in MOSFET integrated circuits. The regulator includes a MOSFET switch which when enabled in a first state connects Vpp to the integrated circuit voltage level, Vcc, and which when disabled in a second state allows Vpp to be driven to levels greater than Vcc. The regulator includes a multipath control circuit for controlling the switch state and for controlling Vpp. A first current path, Iramp, controls the rise-time parameters of Vpp and a second current path, Idis, controls the fall-time parameters of Vpp. The rise-time parameters and the fall-time parameters are separately controlled.
