Directional microphone or microphones for position determination. One or multiple directional microphones are implemented in various locations to perform acoustic wave capture of acoustic waves associated with object (e.g., a player, a gaming object, a game controller, etc.). The generator of such acoustic waves may be co-located with the object (e.g., integrated into the object if the object is a device such as a gaming object, a game controller, etc., or integrated into clothing worn by a player such as on a hat, a jacket, etc.). The acoustic waves described herein may be generated by any number of means/devices including audio output devices, speakers, pulse wave generators, audio oscillators, etc. Moreover, such acoustic waves may be ultrasonic. A game module and/or processing module processes directional vectors associated with positions of the directional microphones when detecting relative maximum amplitude of an acoustic wave emits by an acoustic wave generator.

A method for error-compensated current measurement of an electrical accumulator, including: providing a time window-related estimated charge ascertained by a model-based estimator from operating variables of the accumulator and reflecting the estimated charge that has been withdrawn from the accumulator and supplied to the accumulator within the time window; and detecting the accumulator current supplied to the accumulator and withdrawn from the accumulator during the time window, with a current detection sensor. A zero crossing point in time (estimated charge is essentially zero) and a maximum point in time (the absolute value of the estimated charge essentially has a relative maximum or has a value which is greater than a minimum charge difference) are detected. A current measurement offset error is ascertained at the zero crossing point in time by comparing the estimated charge to the detected accumulator current. The accumulator current is ascertained according to the current measurement offset error, and a current measurement scaling error is ascertained at the maximum point in time by comparing the estimated charge to the detected accumulator current. The ascertained current measurement offset error is subtracted from the comparison result thus obtained, and the accumulator current is compensated for based on the current measurement scaling error. A related device for error-compensated current measurement is also described.

A method for making a multimode fiber optic subassembly includes alignment of an optical detector with a fiber termination of an optical fiber. The output of the optical detector (e.g. photocurrent) can be measured from light being transmitted through the optical fiber and detected by the optical detector. The end of the optical fiber and/or the optical detector can be positioned and angularly oriented in order to obtain relative maximum or peak output of the optical detector for a given position and orientation. The output of the optical detector can be monitored while mechanically manipulating, e.g. bending, flexing, shaking and/or twisting, the optical fiber, in order to verify that the positional relationship between the end of the optical fiber and the optical detector corresponds to a position and/or orientation that provides stable output from the optical detector. If the optical detector output is not stable, the end of the multimode optical fiber and the optical detector can be moved, changing the position and/or the orientation of one or both, until the output of the optical detector is stable during manipulation. If the optical detector output is stable, the end of the multimode optical fiber is fixed to the optical detector. The resulting subassembly, a fiber optic pigtail, can be made by cutting the optical fiber a short distance from the optical detector.
