A method for preventing a task-signal deadlock arising due to contention for a mutex in a real-time operating system (RTOS) includes detecting, by a processing unit, a signal notification sent to a task for execution of a signal handler; identifying, by the processing unit, a mutex to be acquired by the signal handler, when the signal notification is detected; determining whether the identified mutex has been acquired by the task; and utilizing, by the processing unit, an alternative stack for execution of the signal handler, in response to determining that the mutex has been acquired by the task, for preventing a task-signal deadlock during the execution.

Method and apparatus for preventing task-signal deadlock due to contention for mutex in RTOS

An axial flux motor may include a motor housing, a shaft rotatably mounted in the housing, and a stator mounted in the motor housing, and having a stator ring and a through-hole through which the shaft extends. Two rotors may be mounted on the shaft within the motor housing on opposing sides of the stator, each rotor having a plurality of magnets arranged radially on a stator-facing surface thereof. In addition, magnet wire may be wound on portions of the stator, the magnet wire comprising an inner coolant passage disposed within a copper tube, and a green glass coating on an outer surface of the copper tube, the green glass coating comprising glass solids, one or more of surfactants, solvents, and polymers.

An apparatus is configured to collect information related to a first activity and analyze the collected information to determine decision data. The information is stored in a first list of the source processing core for scheduling execution of the activity by a destination processing core to avoid cache misses. The source processing core is configured to transmit information related to the decision data using an interrupt, to a second list associated with a scheduler of the destination processing core, if the destination processing core is currently executing a second activity having a lower priority than the first activity.

An internal combustion engine is provided having at least one turbocharger having a compressor and an exhaust gas turbine, at least two actuating members for controlling a boost pressure by the compressor, a measuring device for measuring at least one measurement signal, and a control device adapted to actuate the actuating members by varying a degree of opening of the actuating members. The control device of the internal combustion engine is configured to calculate a total degree of opening of the actuating members necessary to achieve a desired boost pressure provided by the compressor. This is in dependence on the at least one measurement signal. The control device is also configured to determine the total degree of opening split between each of the at least two actuating members, and to control each of the actuating members according to its individual degree of opening to reach the desired boost pressure.

Systems and methods are described for positioning a Low Altitude Platform Station (LAPS) based drone cells for supporting communication in a 3GPP network. The methods may include receiving at least one feedback parameter from a UE pertaining to a current network traffic flow and mobility with respect of the UE. The UE is selected for an aerial network through a drone base station (DBS) cell based on service requirement determined from the feedback parameter. Further, a position for at least one DBS-cell is determined with respect to the at least one selected UE based on the at least one parameter to serve the selected UE. An aerial-communication link is established between the selected UE and the DBS cell by deploying one or more LAPS as a drone base station (DBS) in accordance with the determined position of DBS-cell to thereby augment a network connectivity of the selected UE.

A system includes a cylinder, a piston, a sensor configured to detect vibrations of the cylinder, piston, or both that correspond with varying pressures within the cylinder, and a controller coupled to the sensor. The controller is configured to receive a first signal from the sensor corresponding with first vibrations of the cylinder and to deduce from the first signal a first operating value of a parameter indicative of peak firing pressure at a first time, to compare the first operating value with a baseline value of the parameter indicative of peak firing pressure to detect a change in peak firing pressure, to receive a second signal from the sensor corresponding with second vibrations of the cylinder and to deduce from the second signal a second operating value of the parameter indicative of peak firing pressure at a second time, and to compare the second operating value with the baseline value to confirm the change in peak firing pressure.

A device receives a new rule construct that includes a source address or a destination address, and at least one parameter, where the new rule construct includes a new rule to be provided to a network. The device identifies network devices, of the network, to which the new rule is to be provided based on the new rule construct, and determines a proper position for the new rule, in a list of existing rules provided in each network device, based on the new rule construct and information associated with the network devices. The device causes the new rule to be provided to and stored in the network devices, at the proper position, in the list of existing rules, determined for each network device.

A parser can be configured to parse source code to generate code for dynamically generating structures at runtime. Any or all of the structure name, keys, and values can be defined dynamically (i.e. at runtime), rather than requiring declaration in the source code. Embodiments include a method in which a source file is parsed to identify an expression creating a dynamic structure with at least one key-value pair. The method can comprise generating a plurality of expressions for creating intermediate data structures which, at runtime, can cause the dynamic structure to be defined as set forth in the declarative expression. The dynamic structure may comprise one or more declared key-value pairs and/or may comprise one or more key-value pairs that are also dynamic.
