Method of real-time regulation compliance for wireless transmitters
All wireless devices must comply with the local radio regulations which are set by international and national regulatory bodies such as the European Telecommunication Standardization Institute (ETSI) for Europe and the Federal Commission for Communication (FCC) for US. A new firmware module is proposed, that will ensure that devices, in all circumstances will comply with the ETSI regulations for single channel emissions in the 868 MHz ISM band. Namely, assuring compliance with the duty-cycle limit, the maximum TX time and minimum TX-off time limit. Such a solution has not been researched mostly due to the popularity of the virtually worldwide 2.4 GHz ISM band which does not have duty-cycle limitations. The wireless sensor networks (WSN) operating in the 868 MHz band have their own niche applications that benefit from the increased signal range. The development and the acceptance of such applications will benefit from the existence of the proposed module implemented in firmware/software. We propose such a solution and demonstrate its implementation on a custom developed node and protocol. Implementation on top of standardized protocol layers is also analyzed. We also analyze the memory, time and energy overheads caused by including the module in the firmware. |

Method and apparatus for processing signals of a spherical microphone array on a rigid sphere used for generating an ambisonics representation of the sound field
Spherical microphone arrays capture a three-dimensional sound field (P(Ωc,t) for generating an Ambisonics representation (Anm(t)), where the pressure distribution on the surface of the sphere is sampled by the capsules of the array.

Electronic camera, computer readable medium recording imaging control program thereon and imaging control method
Determination is made whether or not a cross point coordinate of a zoom value and a degree of luminance belongs to the continuous imaging area of a two-dimensional coordinate plane. When the cross point coordinate is in a single imaging area, since the provability of shake occurrence is low, a first imaging processing is operated. In contrast, when the cross point coordinate is in the continuous imaging area, a shake correction flag representing the execution of the shake correction is set. A multiplane addition composition imaging is not performed uselessly under an imaging condition where the provability of shake occurrence is low. As a result, since the multiplane addition composition imaging is not performed without inevitability, it is possible to avoid a disadvantage that a useless addition processing is executed to thereby generate noise in a shot image stored in an image memory medium. |

Token-based secure data management
In some implementations, tokens that are representative of sensitive data may be used in place of the sensitive data to maintain the security of the sensitive data. For example, data may be separated into sensitive data and nonsensitive data, and at least the sensitive data is securely delivered to a data storage service. The data storage service generates a token that is representative of the sensitive data and stores the sensitive data as secure data. The data storage service may deliver the token to an entity that also receives the nonsensitive data, and the entity may use the token in place of the sensitive data. In some implementations, different tokens are generated each time the same piece of sensitive data is submitted for storage as secure data. Further, in some implementations, access policies define authorizations regarding which entities are able to resolve a token to access the actual sensitive data. |

Method for identifying a short-line fault or a line interruption for a switched inductive load
A method identifies a short-line fault or line interruption in a circuit configuration having a series circuit of inductive load and controllable switching element. The series circuit is connected between high and low potentials of a supply voltage source. A connecting point between load and switching element is connected through at least one zener element to the high or low potential of the voltage source or the control connection of the switching element so that upon interruption of current flow through the load due to switching off the switching element, magnetic energy stored in the load can be reduced by a zener element becoming conductive. After switching off the switching element, the voltage at the connecting point is ascertained and a voltage pulse duration is compared with a first prescribed duration. If the duration is shorter than the first prescribed duration, a line interruption or a short is inferred. |

Control method and control apparatus using control signals to control states of transistors in BUCK-BOOST topology
A control method and a control apparatus are provided. The control method and apparatus are applied to a BUCK-BOOST topology. The method specifically is, processing an output signal of a topology to obtain a pulse width modulation signal, performing an OR operation between the pulse width modulation signal and a first modulation signal to obtain a first control signal so as to control a state of a first transistor on the topology, and performing an AND operation between the pulse width modulation signal and a second modulation signal to obtain a second control signal so as to control a state of a second transistor on the topology. Therefore, the method achieves three topology states and a smooth switchover among the three topology states. In addition, the control circuit is relatively simple, expanding the control scope and improving the control precision. |

DC-DC voltage converter and conversion method
A DC-DC converter comprises a capacitor arrangement and a switching arrangement for controlling coupling of the capacitor arrangement to a converter input during a loading phase and to a converter output during a storing phase. The converter cycles between charge pumping stages and charge holding phases, giving rise to a converter switching frequency. A variable output load is controlled thereby to maintain a constant converter switching frequency. |

Electric power converter to reduce or eliminate erroneous power module abnormality indication
A processor unit in an electric power converter executes detection of an overheating predicted state that is a stage prior to overheating of the IGBTs, a short circuit predicted state that is a stage prior to a short circuit in the arms, and a voltage drop predicted state that is a stage prior to a drop in a control voltage to be supplied to a driver circuit. When none of these predicted states is detected, a determination that an abnormality is not caused in the power module based on a latch signal is made by the processor unit. When an overheating predicted state is detected, the processor unit lowers the duty ratio of a motor control signal. When a short circuit predicted state is detected, the processor unit prolongs the dead time in which the upper IGBTs and the lower IGBTs are both maintained in the off-state. |
