Title: Current sense amplifier with enchanced common mode input range
Inventor: VAMSIKRISHNA PARUPALLI
IPC: H03M1/10
Filed: 2016-06-08
Abstract: An apparatus and method which measures the current through a device such as an audio loudspeaker, comprising an amplifier 412 or plurality of amplifiers (differential input amplifiers 212, 232 A figure 2), a first signal path coupled to the amplifier 412 and a first terminal 304A (figure 3), whereby the first signal path is configured to measure the current through a device such as resistor R204 (figure 2) by measuring the small valued differential voltage across the resistor, which is proportional to the current passing through the resistor. In this system a relatively large common voltage appears on each of the terminals of the current sensing device (e.g Rsense R204), which due to the imperfections of differential operational amplifiers or due to the mismatching of the series and feedback resistors R, GAIN*R results in a component of the common mode voltage appearing on the output of the operational amplifiers or fully differential operational amplifiers. To counteract this effect a common mode rejection system is set in place by employing a second signal path coupled to the amplifier or to another amplifier and which reduced the common mode voltage by level shifting the generated voltage within the second signal path. The first signal path may represent the conventional differential series resistor connections across the resistor to the differential input of the operational amplifier (314A, 314B in figure 3). The second signal path may represent a common mode compensatory signal applied to the inputs of the amplifier (operational amplifier) and connected to the first input via an invertor 380 and by series resistors R382A, R382B (figure 3). The inversion operation is key to the neutralization of the common mode voltage in the operational amplifier input, as the common mode voltage is cancelled by a copy of its own (180 degree) inverted phase shifted signal. The resistive components in the first and second signal path may be combined with capacitor connection to ground to filter Ac common mode signals, using RC filters. A second amplifier may be coupled to the device so as to form in conjunction with two separate analogue to digital converter two ADC paths. The first ADC path measuring the current derived differential mode voltage signal, whilst the second ADC path develops a signal proportional to the common mode voltage. These signals remain in the digital domain, whilst a summing junction (-) and multiplier (x) unit may combine the digital signals to eliminate or reduce the common mode voltage component. The exact value used in the digital multiplication is determined by a calibration gain value 470 stored in a digital memory device.

Title: Method for automatically switching to a channel for transmission on a multi-watch portable radio
Inventor: MUN YEW THAM
IPC: H04W4/10
Filed: 2015-03-24
Abstract: A method for automatically switching to a channel for transmission on a portable radio is provided. In operation, a first microphone is assigned to respond to communications received on a primary channel and a second microphone is assigned to respond to communications received on a non-primary channel. The portable radio receives independent audio communications simultaneously on the primary channel and the non-primary channel when operating in a multi-watch mode. The portable radio determines a signal gain corresponding to a voice command received at the first and second microphones. When the signal gain for the first microphone is larger than the signal gain for the second microphone, the portable radio switches to a first talk-back channel to respond to communications received on the primary channel. Otherwise, the portable radio switches to a second talk-back channel to respond to communications received on the at least one non-primary channel.

Inventor: OHAD SHATIL
IPC: H04W24/02
Filed: 2017-03-16
Abstract: Wireless local area network (WLAN) field coverage is analysed inside a venue/building. A mobile data capture device (handheld 22, vehicle 28) measures coverage data indicative of WLAN coverage from a plurality of access points/base stations 20, in a plurality of locations, and also simultaneously captures image data from camera (40, figure 3) indicative of images of the locations in the venue. A controller correlates the measured coverage data and captured image data at each location. An interface displays the captured time-stamped image data correlated with the measured coverage data at each location (figures 4A, 4B). Impact score value data indicative of the WLAN coverage may also be determined, correlated, and displayed (66, figure 4B) for each location. Measured coverage data may be Received Signal Strength Intensity (RSSI). An analyst may see that a displayed location has a low RSSI, or a high impact score, that is indicative of a cold zone of poor coverage and wish to see the actual environmental conditions at that location from the image data, which might show a physical obstruction (e.g., temporary shelving). The controller locates the mobile capture device at each location by measuring signal strengths of the plurality of access points 20.

Title: Set-up for continuous production of H2 , CO, granulated fertiliser slag from the molten slag and sequestering CO2 from the flue exhaust
Inventor: PRAKASHKUMAR NARASIMHAMURTHY
IPC: F27B9/00
Filed: 2017-10-07
Abstract: A system and method to facilitate continuous production of mainly H2, CO and granulated slag or granulated slag fertilizer from quenching molten slag and cooling post quenched hot granulated solid slag in a horizontal furnace in the presence of a carbonaceous materials layer over a movable layer of externally cooled granulated solid slag. The first stage thermo-chemical reaction occurs when reactant is sprayed to quench the molten slag. A second stage thermo-chemical reaction occurs when a reactant gas is injected to cool the post quenched hot solid granulated slag. A third stage thermo­chemical reaction occurs when the gas generated from former two stages intersect in the reactor chamber space. The third stage thermo-chemical reaction increase the concentration of H2 and CO in the gas stream already containing H2 and CO generated from first and second stage thermo-chemical reactions. The system allows increased surface area interface between all the inputs and the generated gas within the reactor chamber. It also facilitates increased residence time for the reactants to react under appropriate conditions. Thus, making it possible to continuously generate optimum producible quality and quantity of H2 and CO from all the inputs. Simultaneously, granulated slag fertilizer of required mineral composition may be produced by altering the mineral composition of the molten slag prior to quenching. Carbonaceous material such as low rank coal, contaminated industrial waste oil, municipal waste, sludge, shale gas etc. can be converted into H2 and CO fuel. All types of high temperature molten slag generated in industries can be used for this purpose. Cleaned and cooled flue exhaust of an industry containing CO2, O2 and smaller quantities of H2O in the form of water vapour can be used as a reactant gas and converted into H2 and CO fuel. Similarly, CO2, O2 and smaller quantities of H2O in the form of water vapour present in the atmosphere air can also be used as reactant gas and converted into H2 and CO fuel.
