Publication number: 20230370746Abstract: Power consumption is reduced in an analog-to-digital conversion circuit using a TDC. The analog-to-digital conversion circuit includes a comparator, a counter, a time-to-digital converter, and a holding unit. The comparator compares an analog signal with a predetermined reference signal and outputs a comparison result. The counter counts a predetermined count value and outputs a bit string indicating the count value. The time-to-digital converter converts, into a digital signal, a time from when the comparison result is inverted until a least significant bit of the bit string reaches a predetermined value. The holding unit holds the bit string of when the comparison result is inverted.Type: ApplicationFiled: August 11, 2021Publication date: November 16, 2023Inventors: YUKI OZAWA, HIROMU KATO, ATSUSHI SUZUKI

Publication number: 20230028780Abstract: Solid-state imaging elements are disclosed. In one example, an upstream circuit block generates a predetermined reset level and a plurality of signal levels each corresponding to an exposure amount, and causes capacitive elements, different from each other, to hold them. A selection circuit sequentially performs control to connect the capacitive element in which the reset level is held to a predetermined downstream node, control to disconnect capacitive elements from the downstream node, and control to connect the capacitive element in which any of the plurality of signal levels is held to the downstream node. A downstream reset transistor initializes a level of the downstream node when the capacitive elements are disconnected from the downstream node.Type: ApplicationFiled: February 17, 2021Publication date: January 26, 2023Inventors: Luonghung Asakura, Hiromu Kato

Publication number: 20220058095Abstract: In accordance with an embodiment, described herein is a system and method for transaction recovery in a multitenant application server environment. At least one resource manager associated with a partition can be designated as a determiner resource for that partition only, in order to support eliminating transaction logs (TLOG) in processing a two-phase commit transaction. A transaction manager can prepare all other resource managers in the mid-tier transactional system before the determiner resource. Furthermore, the transaction manager can rely on the list of outstanding transactions to be committed that is provided by the determiner resource for recovering the transaction. The transaction manager can commit an in-doubt transaction returned from a resource manager that matches the list of in-doubt transactions returned from the determiner resource. Otherwise, the transaction manager can roll back the in-doubt transaction.Type: ApplicationFiled: November 4, 2021Publication date: February 24, 2022Inventors: Paul Parkinson, Hiromu Kato, Arjav Desai

Patent number: 11057272Abstract: In accordance with an embodiment, described herein is a system and method for transaction support in a multitenant application server environment. A system can provide for transaction support via a transaction manager. The transaction manager can be associated with one or more objects, including a configuration object and a runtime object. The configuration object can allow for a partition administrator to override globally-set parameters for transactions, including transaction timeout time. The runtime object can allow for a partition administrator to monitor partition-scoped transaction statistics. Furthermore, the transaction manager can additionally account for resource group migration within the multitenant application server environment.Type: GrantFiled: September 25, 2015Date of Patent: July 6, 2021Assignee: ORACLE INTERNATIONAL CORPORATIONInventors: Paul Parkinson, Hiromu Kato, Arjav Desai
