Patent number: 11870089Abstract: A battery cell pack has a plurality of battery cells that are assembled into a prismatic frame, with deformable separators interposed to accommodate elastic and plastic deformation caused by cyclic and acyclic expansion and contraction thereof during charging and discharging over the life of the battery cell pack. The battery cells are arranged in a horizontal stack within the prismatic frame, and the deformable separators are interposed between subsets of the battery cells. The deformable separators exert compressive force on the subsets of the battery cells along a longitudinal axis that is defined by the horizontal stack. The compressive force exerted by the deformable separators is at least a minimum force over a service life of the battery cell pack.Type: GrantFiled: March 15, 2022Date of Patent: January 9, 2024Assignee: GM Global Technology Operations LLCInventors: Andrew C. Bobel, Anil K. Sachdev, Patrick H. Clark, Pooja Suresh, Ran Wu, Jermain E. Onye, William Y. Chen, Li Yang, Chao Hu, Yunshan Liu, Kuo Sun

Patent number: 8627302Abstract: A method of reproducing runtime environment for debugging an application includes reading an optimizer file from a non-volatile storage medium. The optimizer file includes a runtime environment, application definition information, and a log. The log includes summaries of events, actions, and a time mark of occurrence for each of the actions. A runtime environment for debugging the application is then defined and the application runtime is set up using the application definition information in the optimizer file. Further, the method includes running the application, attaching an optimizer, and triggering each of the actions to occur at a time mark of occurrence associated with each of the actions. Then, each of the actions and associated events is analyzed by comparing the events produced by running the application with the events in the optimizer file. If a fault is produced by the triggering, a debugger is invoked to analyze the fault.Type: GrantFiled: November 27, 2007Date of Patent: January 7, 2014Assignee: Oracle America, Inc.Inventors: William Y.

Patent number: 8521760Abstract: Techniques for selectively translating resource requests from a program running on a computer system are disclosed. The resource request may be a request to access a file, library file, API, etc. The resource request may be a system call or library call. The computer program may be non-native to the computer system. Translation of resource requests may occur within the operating system or outside it. A resource request containing a reference to a first path and file name may be selectively translated by altering the resource request to contain a reference to a second path and file name. After selectively translating a request, he request is caused to be serviced. A resource request may be serviced by forwarding it to an operating system, and a result may be sent back to the program.Type: GrantFiled: December 30, 2008Date of Patent: August 27, 2013Assignee: Oracle America, Inc.Inventors: Abhinav Das, William Y.

Patent number: 8473930Abstract: A method for executing non-native binaries on a host computer architecture comprises receiving the guest executable binary into a computer readable medium. The guest executable binary is executed on the host computer architecture by translating the guest executable binary into a translated executable binary. Each instruction of the translated executed binary is then executed on the host computer architecture. Signals are responded to by placing signal information on a signal queue and deferring signal handling until a safe point is reached. A computer system implementing the method is also provided.Type: GrantFiled: November 5, 2008Date of Patent: June 25, 2013Assignee: Oracle America, Inc.Inventors: Abhinav Das, Jiwei Lu, William Y.

Patent number: 8346531Abstract: A method for executing non-native binaries on a host computer architecture comprises receiving a guest executable binary encoded on a computer readable medium. The guest executable binary is executable on a first computer architecture. Moreover, the guest executable binary includes a mutex lock encoded instructions for implementing a mutex lock. The guest executable binary is then executed on the host computer architecture by first translating the guest executable binary to a translated executable binary. The encoded instructions for implementing a mutex lock are translated by mapping the mutex lock to an instance of a compound mutex lock data structure. A computer system implementing methods for executing non-native binaries on a host computer architecture is also provided.Type: GrantFiled: November 5, 2008Date of Patent: January 1, 2013Assignee: Oracle America, Inc.Inventors: Abhinav Das, Jiwei Lu, William Y.

Patent number: 8230402Abstract: A method for testing and debugging of dynamic binary translation wherein a dynamic binary translator allows a target binary to be executed transparently on a host machine having a different computer architecture than the target machine involves selecting a minimum set of target machine states for simulation at run-time. A series of target machine instructions from the target binary is translated into a series of host machine instructions. During translation, a plurality of check points are inserted into the series of host machine instructions. During translation, a plurality of verification points are inserted into the series of host machine instructions. The series of host machine instructions, including the check points and verification points, are executed. Execution of a check point determines a simulated target machine state. Execution of a verification point sends information pertaining to simulated target machine states to an external verifier.Type: GrantFiled: September 30, 2007Date of Patent: July 24, 2012Assignee: Oracle America, Inc.Inventors: William Y.

Patent number: 6732356Abstract: Systems and methods are provided through which compare instructions in computer code are eliminated partially resolving the predicate of the compare instructions. Partially resolved predicates are used to reduce the number of compares generated during the prediction phase of the compiler. In a partially resolved predicate, the predicate name is defined along the same paths as the fully resolved predicate counterpart, but it can be used to guard a subset of the instructions of the fully resolved predicate name. A partially resolved predicate is generated for predicate names which are only valid in a restricted control flow region. One or more of the control flow edges are ignored when computing control dependence. The predicate name relies partially on the actual ignored control flow edge to prevent incorrect usage of the predicate name.Type: GrantFiled: March 31, 2000Date of Patent: May 4, 2004Assignee: Intel CorporationInventor: William Y.

Patent number: 6637026Abstract: When compiling software for a processor that supports predication, an alerting instruction can be inserted to alert a global register allocator to map particular virtual predicates into the same physical registers. Redundant predicate generating instructions are removed from the resulting program. The alerting instruction can be a predicate copy pseudo-opcode. When the register allocator maps the virtual predicates into the same physical register, the predicate copy pseudo-opcode is removed. When the register allocator does not map the virtual predicates to the same physical register, the predicate copy pseudo-opcode is replaced by an instruction that will perform a predicate copy.Type: GrantFiled: March 1, 2000Date of Patent: October 21, 2003Assignee: Intel CorporationInventor: William Y.
