Abstract: A tool system includes a tool, an image capturing unit, a processing unit, and a set state detection unit. The tool is a portable tool including a driving unit to be activated with power supplied from a power source. The image capturing unit is provided for the tool and generates a captured image. The processing unit intermittently performs identification processing of identifying a work target based on the captured image. The set state detection unit detects a state where the tool is set in place on the work target.

Abstract: A tool system includes a portable tool, an image capturing unit, and a control unit. The tool includes a driving unit to be activated with power supplied from a power source. The image capturing unit is provided for the tool and generates a captured image. The control unit controls the tool based on the captured image. The control unit has a work support capability. The work support capability is the capability of placing a restriction on operation of the tool when a work target identified based on the captured image does not conform to a working instruction defined by a working procedure. The control unit suspends, when finding a lifting condition satisfied while performing work-support-enabled operation, the work-support-enabled operation and thereby lifts the restriction on the operation of the tool.

Abstract: A communication apparatus includes a first communication circuit, a second communication circuit, and a controller. The first communication circuit performs wireless communication with a gateway using a first communication system. The second communication circuit performs wireless communication with the gateway using a second communication system having a higher transmission speed than the first communication system. The controller is configured to activate the second communication circuit when the first communication circuit receives an activation request signal from the gateway, and to establish a link between the second communication circuit and the gateway when the first communication circuit receives a connection request signal from the gateway after the second communication circuit is activated.

Abstract: Disclosed is a wireless transmitter/receiver provided with: a local oscillator which oscillates at a predetermined local oscillator frequency; a mixer which mixes a local oscillation signal of the local oscillation frequency outputted from an output terminal of the local oscillator and a radio signal received by an antenna; a modulation circuit which modulates the local oscillator signal and generates a radio signal; and a transmission/reception switching unit which selectively switches over between a reception state in which the output terminal of the local oscillator is connected to the mixer and a transmission state in which the output terminal is connected to the antenna without passing through the mixer.

Abstract: A radio communication system minimizes power consumption against noises. The system includes a first radio terminal (10A) with a first transmitter (40A) for transmitting a first data indicative of a specific event, and a second radio terminal (40A) with a battery (14B) and a receiver (20B). The first radio terminal (10A) includes a first bit interpolator (32A) which inserts a check bit pattern of “01010101” at a predetermined cycle into one frame of the first data. The second radio terminal (10B) has a second power controller (60B) which intermittently activates the second receiver (20B) at predetermined intervals in order to receive the bit-interpolated data from the first transmitter.

Abstract: The wireless communication system includes a first wireless terminal (10A) and a plurality of second wireless terminals (10B). The first wireless terminal (10A) transmits a synchronization signal. The synchronization signal comprises a plurality of reference signals each including a reference data indicative of a relation between the corresponding reference signal and a reference time. The second wireless terminal (10B) includes a timer (13) configured to output an activation signal at a regular interval, a control unit (14), and a synchronization unit (15). The control unit (14) activates a wireless receiver (123) each time it receives the activation signal from the timer (13). When the wireless receiver (123) receives the synchronization signal, the synchronization unit (15) refers to the reference data obtained from the earliest reference signal and a reception time of the earliest reference signal, and determines the reference time.

Abstract: A power saving wireless fire alarm system has a master station and a plurality of battery-powered fire detecting terminals linked for wireless communication with each other. Upon detection of a fire occurrence at one of the fire detecting terminals, the fire detecting terminal transmit a fire detection message to a master station which in turn transmit a wake-up message to the other fire detecting terminals and thereafter a fire information message which starts a multiple synchronous communication between the master station and the fire detecting terminals. Each fire detecting terminal has a power controller which selects an intermittent reception mode of activating its own receiver only intermittently until receiving the wake-up message or information indicative of the fire occurrence, and select a constant operation mode thereafter to make the fire detecting terminals be ready for the multiple synchronous communication commenced by the fire information message from the master station.
