A safety control system for vehicles including a telephone and sensors for sensing a potentially dangerous condition and for automatically disabling the telephone when sensing such condition. The sensors include two sensors mounted on a steering member to be gripped by the two hands of the driver of the vehicle and effective to disable an operation of the telephone when the two hands of the driver are not sensed as gripping the steering member while the vehicle is in motion. The sensors may also disable the telephone, and / or actuate a signaling device, when sensing other driver conditions or vehicle conditions in which the distraction of the driver by a telephone conversation could increase the risk of accidents.

A multifunction safe electric pressure cooker includes a lid, an outer body, a warming container, a control panel, an inner tank, a sealant washer, a heating plate under the inner tank, and a control device. The control device comprises a control circuit, a pressure switch, and a temperature control device. The lid has a floating valve, a pressure discharging valve, and a safety valve. Between the heating plate and the warming container there is a spring device. Under the heating plate is a pole. The control device employs a sensor to determine whether the inner tank is placed in the cooker. Between the lid and the body sets a lid safety control switch that connected to the control circuit. The electric pressure cooker is more convenient and durable, can fry and sauté food, and includes multiple safety devices.

A method and apparatus for pressure infusion and temperature control of infused liquids includes a receptacle for receiving a liquid-filled bag containing intravenous solution or other liquid and an inflatable pressure device. The inflatable pressure device is disposed within a pressure device bag and is positioned proximate the liquid-filled bag in the receptacle. The inflatable pressure device expands within the pressure device bag upon inflation and exerts pressure on the liquid-filled bag. A heating element may be disposed on the inflatable pressure device bag to heat the liquid-filled bag to a desired temperature. The liquid may alternatively be maintained at a desired temperature, while flowing to a patient via a heating assembly disposed along a tube. The heating assembly includes a sleeve having a slot for receiving the tube and a plurality of individually controlled heaters. An infrared sensing device is mounted proximate a drip chamber to ascertain a drip count, while a temperature sensor is disposed within a holder that is positioned toward the entry site on a patient. A heat controller controls the heaters based on a drip count, while a safety controller disables heater operation in response to liquid temperature exceeding the desired temperature. Thus, the safety controller and heat controller, in combination, control the heating assembly heaters based on liquid temperature and flow rate, respectively. Alternatively, the liquid-filled bag may be heated to a desired temperature whereby the heating assembly includes a single heater controlled by a controller to maintain the liquid at the desired temperature during infusion of the liquid into a patient.

According to one aspect of one embodiment of the present invention, a safety control system for vehicles, includes, a communication device having at least one of an input accessible from within the vehicle and an output communicated within the vehicle, at least one sensor operable to sense at least one condition related to vehicle operation, and a controller communicated with the sensor and the communication device to selectively suppress at least one of said input and said output in response to a sensed parameter of said at least one condition being outside of a threshold. When an input is suppressed, the driver is prevented from accessing or inputting information into the communication device. When an output is suppressed, communication between the device and the driver of a vehicle is suppressed to, among other things, avoid distracting the driver during certain driving situations or conditions relating to the driver, vehicle and / or environment.
