Title: Determination of flow rate and fluid temperature
Inventor: OLIVER PARSON
IPC: G01M3/28
Filed: 2017-11-02
Abstract: A method for determining the flow rate in a pipe includes measuring a temperature difference between the pipe and the temperature of the surroundings of the pipe and dividing this difference by the difference between the temperature of the fluid entering the pipe and the temperature of the surroundings of the pipe. A non-linear conversion between the ratio derived in this way and the flow rate is used to estimate the flow rate. Also disclosed are methods for estimating the temperature of the fluid entering the pipe using either the temperature of the pipe or the local air temperature. The first method comprises: periodically receiving measurements of the temperature of the conduit; determining an extremal temperature of the conduit over a preceding time period of predetermined length; and using the determined extremal temperature as an estimate for the fluid temperature. The second method comprises: determining a rolling average of local air temperature over a preceding predetermined period; and using the determined rolling average of local air temperature as an estimate for the fluid temperature.

Title: Three position interventionless treatment and production valve assembly
Inventor: JUAN CARLOS FLORES PEREZ
IPC: E21B43/25
Filed: 2016-08-31
Abstract: A first sleeve is shifted with a ball landed on a seat to open treating ports. At the conclusion of the treating such as fracturing, another ball is dropped on a seat in an adjacent sleeve. The adjacent sleeve shifts to contact the initial sleeve that was shifted earlier. When the sleeves abut the treating ports are closed by the second sleeve and the production ports that are preferably screened are also opened by the shifting of the second sleeve against the first sleeve. The first sleeve hits a travel stop in the housing to produce the full open position for the treating ports. The balls can be progressively larger in a bottom up direction for the procedure or the balls can all be the same size as the landing of a ball on the first sleeve reconfigures the sleeve above for the same sized ball.

Title: Vehicle access system
Inventor: HOWARD SISWICK
IPC: G07C9/00
Filed: 2018-04-03
Abstract: The invention relates to vehicle access methods, such as keyless or passive entry passive start (PEPS) systems. The vehicle 110 scans 200 for a first signal 202 from a first device, e.g. mobile phone 154, using a first communication channel, e.g. Bluetooth (RTM, short-range wireless protocol). A received signal strength indication (RSSI) 210 of the first signal is compared to a threshold 212. If the RSSI exceeds the threshold, a challenge signal 216 is sent to a second device, e.g. key fob 112, using a second channel, e.g. low-frequency (LF) radio. A vehicle access system, such as unlocking doors, is controlled 220 depending on a signal received 218 in response to the challenge signal. The first signal may include an identifier that the first device is an approved device. The vehicle may compare the signal strength at multiple antennas to determine an approach vector 206 for the first device. The challenge signal may be transmitted on the side of the vehicle from which the first device is approaching. Power use is reduced by using detection of the first device to anticipate the proximity of the key fob, and only then activating the LF radio 214.
