Latest Patents
Ishiguro’s recent inventions showcase his expertise and forward-thinking approach. One notable patent is for a radio pager housing that features openings for replacing a crystal oscillator. This design allows for a radio pager to change its reception frequency as desired, utilizing a replaceable crystal oscillator. The casing is ingeniously designed with both a first opening for attaching or detaching the oscillator from a printed circuit board and a second opening for easily inserting or withdrawing the oscillator from the casing.
Another of Ishiguro's patents relates to a radio communication apparatus capable of notifying the reception of a call. This device selectively receives call signals and employs a counting mechanism to produce a count for each signal received. The control section compares this count with multiple threshold values, allowing it to determine a controllable perceptual notifying mode, which can include both audible and visual notifications. The audible mode adjusts the volume based on the count, while visual displays are provided by elements like light-emitting diodes. This innovative approach helps alert users effectively to incoming calls.
