Title: Apparatus for evacuating a corrosive effluent gas stream from a processing chamber
Inventor: CHRISTOPHER BAILEY
IPC: F04C19/00
Filed: 2015-07-22
Abstract: An apparatus for evacuating a gas stream of corrosive fluid exhausted from a processing chamber, comprises a dry pumping arrangement 22, a liquid ring pump 26, a separator 34 and an abatement arrangement 40. The liquid ring pump 26 is arranged for evacuating the gas stream of corrosive fluid from the dry pump and at least partially reducing the corrosive fluid content of the gas stream by dissolving the corrosive fluid into a service liquid of the liquid ring pump. The service liquid is preferably water or aqueous solutions that are reactive with, or are suitable solvents for, the gases being pumped. The separator is suitable for separating a gas stream remaining from the service liquid and gas stream mixture exhausted from the liquid ring pump. The abatement arrangement is suitable for treating the separated remaining gas stream exhausted from the separator. The apparatus may be used to treat waste streams containing one or more silicon-containing or halogen-containing gases which are used as a precursor in the manufacture of a semiconductor device.

Title: System and method for augmenting healthcare-provider performance
Inventor: SHAKIL IAN
IPC: G16H10/60
Filed: 2014-01-29
Abstract: A system and method for augmenting healthcare-provider performance employs a head- mounted computing device that includes camera and microphones to capture a patient encounter and events immediately before and after: video, dictation and dialog. Wearing the device by the provider during the encounter permits normal interaction between provider and patient, encouraging the provider to maintain focus on the patient. An "ears-open" earpiece delivers audio data from a remote location without obstructing the ear canal. Augmented reality multimedia is displayed via a heads-up display over the eye(s). Real-time capture of audio and video enables dramatic cost reductions by saving doctor time. Using the system, a doctor no longer need spend hours daily on transcription and EHR entry. A patient encounter is captured and transmitted to a remote station. Relevant parts of the encounter are saved or streamed, and updates to an EHR are entered for provider confirmation after the patient encounter.

Title: Ultrasonic locationing system using a dual phase pulse
Inventor: Russell E Calvarese
IPC: G01S1/74
Filed: 2015-07-16
Abstract: An ultrasonic locationing system using a dual phase pulse includes an emitter emitting two consecutive frequency bursts, each having a different phase, within one ultrasonic pulse. A receiver microphone receives the ultrasonic pulse, and a processor runs an amplitude-based detection algorithm on the pulse for a band of frequencies of interest and detects a first burst of the pulse within the proper frequency band and having an amplitude exceeding a threshold. Whereupon, the processor determines a relative phase difference between the first burst and a second burst of the pulse and determines whether the relative phase difference is within a predetermined acceptance window, indicating that the pulse is valid for use in locationing the emitter and associated mobile device.

IPC: H03L7/087
Filed: 2017-10-12
Abstract: A phase locked loop 300 comprises a voltage controlled oscillator (VCO) 304 and a first phase detector (PD) 302. The first PD 302 receives a reference signal and the output signal of the VCO 304. The PLL circuit further comprises a second phase detector 310 and a switching device 314. The second PD 310 receives the reference signal and the output of the VCO 304. The second PD 310 may be external. The operating frequency of the first PD 302 may be lower than that of the second PD 310. The first and second phase detectors 302, 310 may be coupled selectively to the VCO 304 via the switching device 314. The VCO 304 and the first PD may be integrated on a single PLL chip. In operation, the switch 314 may initially be set to the integrated phase detector 302. Once lock is achieved, the switch 314 may be changed to select the external detector 310. The external detector 310 may be a high quality, high frequency, phase detector. The external loop may employ a mixer and no divider (fig.6). As a result, the output phase noise is very low, without the need for a conventional pre-tuning system.

Title: Leading zero anticipation
Inventor: DAVID RAYMOND LUTZ
IPC: G06F7/499
Filed: 2017-12-05
Abstract: A data processing device calculates the difference 110 between the significands of two floating point numbers. To normalise the difference, an intermediate number w is generated 130. This number has either the same number of, one more or one less leading zero than the difference between the significands. The number of leading zeroes in w is counted 140, and input to a left shifter 160 to normalise the difference. In parallel to the counting, two masks are generated from w 150. Both masks have a one in the location of the most significant non zero bit in w and zeroes in the more significant bits. The l mask has zeroes in the less significant bits. The s mask has ones in the less significant bits. The l mask is used to detect an overflow using a logical and operation between the mask and bits of the difference 170. If an overflow has occurred, the difference is shifted right one bit 180. The s mask is used to return trailing bits of the difference by performing a logical and with a subset of the bits of the difference 170. This may be used to generate a sticky bit.

Filed: 2018-07-26
Abstract: An authentication system configured to perform an authentication process by using a template generated from biometric data. The authentication system includes a first server, and a second server. The first server generates a first random number used for generating/converting the template from the biometric data.

A signature random number is generated by electrical signing of the first random number by using a secret key, this may be carried out by a trusted third party. The signature random number is then transmitted to the second server. The second server verifies the electrical signing by using a public key that corresponds to the secret key, and stores, into the second memory, the signature random number when verification of the electrical signing succeeds.

A second intermediate diffractive structure 8 or 6 may have diffractive features at a second angle that expand the light in an opposite direction to the first intermediate structure. The angles of the first and second diffractive features may be equal and opposite. The first 6 and second 8 gratings may be: spaced apart on the waveguide; or at least partially overlaid as a pair of crossed gratings (106, Fig. 2). The output diffractive structure 10 may comprises two diffractive optical elements, each provided in a photonic crystal, overlaid on one another in or on the waveguide. The two diffractive optical elements may receive light from the intermediate diffractive optical element and couple it towards the other diffractive optical element thus providing outcoupled orders towards a viewer (Fig. 7B or Fig. 8B).
