Patent GB-2614727-A (GB)
Title: Shifting the frequency of a received signal
Inventor: HASHEM ZARE-HOSEINI
IPC: H04B1/26
Filed: 2022-01-14
Abstract: This application concerns a converter for shifting a frequency of a received input signal (Sig1, Sig 2) to form an output signal at a predetermined intermediate frequency band. The converter includes a mixer (20A, 20B, Fig. 2) driven by a local oscillator (L01, Fig. 2). The converter further comprises control circuitry configured to select the local oscillator to be higher than a frequency of the received input signal (high-side injection, LOh) or lower than a frequency of the received signal (low-side injection, LOl). High-side injection or low-side injection is selected in dependence upon current conditions. The current conditions may include: i) the strength of an image frequency band, IM_ob1, IM_ib1, IM_ib2, IM_ob2; ii) a quality of a signal output from the converter; or iii) the proximity an input signal to the edge of the Ku band used to carry the input signal. In the embodiment of Figure 4, all three of these current conditions are considered together. Preferably a further mixer (22, fig. 2) and a further local oscillator (L02, fig. 2) are provided for down-conversion from IF to baseband. In this case, the current conditions may involve considering the strength of harmonics of the baseband signal.

Title: Solid oxide fuel cell system high-temperature component connecting structure and new energy automobile
Inventor: JIANHONG GAO
IPC: H01M8/2475
Filed: 2020-10-06
Abstract: A high-temperature component connecting structure of a solid oxide fuel cell system. In order to ensure the high-temperature working condition of the solid oxide fuel cell system, when a high-temperature component is supported by a bottom supporting plate and a fixed mounting plate, a heat insulation plate is arranged between the high-temperature component and the bottom supporting plate to reduce the heat conduction to the high-temperature component and the heat loss and raise the heat efficiency. Meanwhile, because the heat insulation plate has a low strength and a low thermal expansion coefficient, in order to counteract the axial expansion amount of the bolts during work at high temperature and ensure a stable supporting structure of the heat insulation plate, when the heat insulation plate, the bottom supporting plate and the fixed mounting plate are locked through the connecting bolts, supporting columns are arranged in the heat insulation plate in the thickness direction of the heat insulation plate and are sleeved on the connecting bolts to bear the locking force of the connecting bolts to avoid deformation of the heat insulation plate under pressure and ensure the stability of the heat insulation structure. A new energy automobile includes the foregoing solid oxide fuel cell system high-temperature component connecting structure

Title: Methods and systems employing enhanced block floating point numbers
Inventor: NEIL BURGESS
IPC: G06F7/483
Filed: 2022-08-01
Abstract: In a data processor, an input value having a sign, an exponent and a significand is encoded by determining an exponent difference between a base exponent and the exponent. When the exponent difference is not less than a first threshold, only the exponent difference, or a designated value, is encoded to a payload of the output value and one or more tag bits of the output value are set to a first value. When the exponent difference is less than the first threshold, the significand and exponent difference are encoded to the payload of an output value and, optionally, the one or more tag bits of the output value. A sign bit in the output value is set corresponding to the sign of the input value, and the output value is stored.

Title: An ancillary water heating system
Inventor: TOBY CHAMBERLAIN
IPC: F24D17/00
Filed: 2023-04-03
Abstract: A supplementary water heating system 200 comprises a pipe 20 for transferring water heated by a primary heater (10, figure 1), e.g. boiler or heat pump, to a water outlet 50, and a secondary heater 30 to heat water flowing towards the outlet. A control unit 70 communicates with at least one temperature sensor 40A,40C arranged on the pipe to monitor water temperature in the pipe. The control unit commands the secondary heater: to activate when the at least one temperature sensor (e.g. upstream temperature sensor 40A) detects a temperature below a first pre-set temperature; and to deactivate the secondary heater when the at least one temperature sensor (e.g. upstream temperature sensor 40A and/or downstream temperature sensor 40C) detects a temperature at or above the first pre-set temperature. A short cycling prevention mechanism is operative, after deactivation of the secondary heater, to prevent reactivation of the secondary heater until the temperature detected by the at least one temperature sensor (e.g. downstream temperature sensor 40C) drops to or below a second pre-set temperature that is ideally at least 3 degrees Celsius below the first. Ideally activation is not possible unless a flow sensor 40B detects water flow.

Title: A system and method for autonomously fingerprinting and enumerating internet of thing (IOT) devices based on NATED IPFIX and DNS traffic
Inventor: Lee Joon Sern
IPC: H04L43/026
Filed: 2023-01-16
Abstract: Fingerprinting and enumerating Internet-of-Things (IoT) devices based on Network Address Translated (NAT-ed) traffic. The system comprises a grouping module (GM) 110, a Term Frequency-Inverse Document Frequency (TF-IDF) vectorizer 112 and an IoT detector and enumerator (IDE) 114. The GM retrieves Domain Name System (DNS) records from the NAT-ed traffic, groups the records based on time-period and source internet-protocol (IP) addresses, and retrieves domains associated with the records. Domains not found in a database generated from records of known IoT devices are removed. The TF-IDF vectorizer generates IoT DNS signatures based on DNS records of known IoT devices. The signatures comprise a list of TF-IDF vectors and a list of normalized TF-IDF (N-TF-IDF) vectors. The distances between each TF-IDF vector in the list exceed a first similarity threshold and distances between each N-TF-IDF vector in the list of N-TF-IDF vectors exceed a second threshold. TF-IDF vectors are computed for the group of domains obtained from the GM. The IDE module computes constituents of the TF-IDF vectors based on the TF-IDF vectors and a Moore-Penrose pseudo-inverse-matrix of the IoT DNS signatures. The constituents of the TF-IDF vectors represent identities of IoT devices and counts of the IoTs that generated the NAT-ed traffic.

Abstract: An apparatus and method for directing accelerated electrons to at least part of one surface of one ophthalmic mold piece prior to filling with monomer and lens polymerization. In particular it has been found that generation of the ionized oxygen by means of a corona treatment electrode sufficiently increases the adherence of the polymer to the mold piece so treated. In the preferred embodiment, the flange around the convex, male piece of the lens mold is corona treated so that when the mold pieces are separated after lens polymerization, the flashing of excess polymerized material surrounding the lens cavity adheres to that male, convex piece flange while the lens is removed with the female, concave piece. <IMAGE>

Abstract: To provide an exhaust heat recovery power generation plant for a sintering facility in which it becomes possible to effectively recover exhaust heat from a sintering device in addition to a sintered ore cooler while controlling the sulfation of anhydrous sulfuric acid droplets included in the exhaust gas of the sintering device. [Solution] An SM boiler (10) heats all or part of the hot water generated by an SC boiler (30) by introducing the high temperature portion of exhaust gas from a sintering device (1). At this point the temperature of the hot water supplied to the SM boiler (10) is controlled so as to maintain the temperature of the exhaust gas in the exhaust gas outlet of the SM boiler (10) above the acid dew point.

Abstract: In chemical light devices comprising a chemi-luminescent mixture with a first fluorescer contained in a transparent or translucent container, a second fluorescer is incorporated in the walls of the container to shift at least part of the emissions from the device from the shorter wavelength emission of the first fluorescer to a longer wavelength emission of the second fluorescer. The second fluorescer has an absorption spectrum substantially overlapping the emission spectrum of the first fluorescer. The shift is usually about 20 to 100 nanometers and may be as much as 200 nanometers.
