Example embodiments involve an enhanced paging system, executed through novel hardware components, to facilitate a client device to pass incoming messages off, through Wi-Fi or cellular data, to a central server. This central server handles a response request, and sends the message to a corresponding pager address found within a pager network, allowing a closed loop two-way communication handled through a graphical user interface which may be displayed at the client device.

An instant alert notifier and docking station for preferred use in emergency situations. Preferably, several notifiers and docking station combinations will be located through a building or location. In a preferred use, the user presses a button and pulls the device cover, which causes the instant alert notifier to preferably perform some or all of the following functions (1) snaps a still image of the person removing the notifier, (2) triggers a code red alert and/or activates flashing red LEDS on the mounting/docking stations where they are located throughout the building/in all locations and (3) switches from a front to a rear camera operation. Using the notifier, real time, time- and date-stamped video, audio and/or still images can be captured and uploaded to off-site or on premises law enforcement and first responder devices. The pressing of the button or removal of the notifier from the docking station can also cause the system to stream live video, audio and/or images to the first responders/emergency responders from all of the other notifiers in the building still contained within their corresponding docking stations.

A culinary mapping tool for detecting cooking status in a pot, comprising a sound sensor (21) capable of directly or indirectly collecting audio signal within a pot body (11) of a cooking pot, and a spectrum analysis terminal for receiving the signal from the sound sensor (21). The spectrum analysis terminal comprises an audio receiver (22), a filter (23), an audio converter (26), and an audio spectrum output device connect in sequence for signal transmissions. Owing to the sound sensor (21) configured to collect audio signal from the pot body (11) of the cooking pot, a user can hear a degree of doneness of food and gain knowledge of cooking status of the food in the pot without opening the pot. The signal collected by the sound sensor (21) is received by the spectrum analysis terminal, and is then subject to noise filtering performed by the filter (23) and conversion to form an audio spectrum segment. The audio spectrum segment can be displayed in various audible or visible formats so as to provide a more direct sound or view for understanding the cooking status within the pot, thereby offering an ergonomic means of assessing and determining a degree of doneness of food. A culinary mapping and evaluation method is also provided which allows visual understanding of cooking status within a pot and can be used to evaluate a degree of doneness of food.

A mobile telephone adapts to use as a gundog training tool by interfacing with a dog collar using a wireless communication device, such as a WWAN text or IP interface, a WLAN interface or a radio transceiver that couples to the mobile telephone and is accessible to a training application running on the mobile telephone. The dog collar includes a GPS receiver to provide position information to the mobile telephone and a shock device to provide training stimulus to the dog. A wireless headset interfaces with the mobile telephone to provide audible indications of position to an end user, such as a dog point and tone indicators of directions to the dog. A wireless handset interfaces with the mobile telephone to accept inputs for application to the collar, such as training stimulus.

A Bluetooth service call system for a customer calling a waiter to provide service content in the business area includes a Bluetooth pager. The Bluetooth pager further includes at least one trigger button for the customer to operate a trigger button to send a service request message; a wireless base station for receiving a service request message and sending a service message; a wireless receiving device, worn by the waiter for receiving the service message; and a cloud console for setting the trigger button corresponding to the service content and saving the Bluetooth pager's location table and the service table. Under such conditions, the Bluetooth service call system can change the service content of the trigger button by simple setting and be widely utilized in various applications that require different service.

An apparatus includes a wireless transceiver and a processor. The wireless transceiver may be configured to communicate wirelessly via a wireless network with an annunciator remotely located from the apparatus and a plurality of call light boxes remotely located from the apparatus. The processor may be configured to (i) control reception of an alarm message from one or more of the call light boxes in response to an event, (ii) illuminate a hall indicator in response to reception of the alarm message, (iii) receive a cancellation message from at least one of (a) one or more of the call light boxes and (b) the annunciator that cancels the event, and (iv) extinguish the hall indicator in response to cancellation of the event. The hall indicator may change color over time until the event is canceled.
