Title: Redox battery
Inventor: JONATHAN GOLDSTEIN
IPC: H01M8/249
Filed: 2021-01-25
Abstract: A redox battery comprises individual cells 100, each having an electrolyte pair including an anolyte 130 and catholyte 125 separated by a membrane 135, wherein the electrolyte pair of each of the individual cells is hydraulically independent of the electrolyte pair of at least one other of the individual cells.

Preferably, all the cells are sealed and hydraulically independent of each other. An agitation mechanism 165, 170 is preferably provided to agitate the anolyte and/or catholyte, such as by pumping, gas sparging or hydrogen bubbling. Various redox active species may be used in the cells, such as an iron/ferric chloride redox pair system.

Filed: 2021-09-30
Abstract: A consumer electronic device 1 includes a low power (e.g. pyroelectric) sensor 8 arranged to detect the presence of a person 6, for example to switch from standby to full power mode. The sensor may output a small analogue signal which is input to a microcontroller 7 for amplification and digital conversion. The microcontroller is configured to supply power to the sensor, for example by configuring an integrated reference voltage source as an input to an integrated operational amplifier which is used to supply power to the sensor. This provides a stable low power supply, thereby reducing noise and false triggering of the sensor. Also, there is no need to provide an additional power supply for the sensor, so reducing the number of components required and allowing for a low-cost and compact sensing circuit.

Title: Preemptive staging for full-stride destage
Inventor: LOKESH MOHAN GUPTA
IPC: G06F12/08
Filed: 2021-03-30
Abstract: There is a method for improving destage performance to a RAID array. The method periodically scans a cache for first strides that are ready to be destaged to a RAID array. While scanning the cache, the method identifies second strides that are not currently ready to be destaged to the RAID array, but will likely be ready to be destaged during a subsequent scan of the cache. The method initiates preemptive staging of any missing data of the second strides from the RAID array into the cache in preparation for the subsequent scan. Upon occurrence of the subsequent scan, the method destages, from the cache, the second strides from the cache to the RAID array.

Title: Portable tree vibrator
Inventor: NAKOS ATHANASIOS
IPC: A01D46/26
Filed: 1989-07-20
Abstract: The portable tree vibrator (see detailed figure 1 to 18) is based on the principle of centrifugal force, which by applying rotation close to the center imparts vibrations onto the tree when placing (hanging) the vibrator head on the tree branch. Thanks to the opposing torques and the concordance of vibrations, this vibration cannot cause the trees any damage or injury and it cannot damage the shoots or the fruit-bearing buds while the optimal efficiency and the easy use of the vibrator (low weight, hanging of the vibrator on the tree branch) ensures a very easy and clean harvest that can produce optimum results.
