Abstract: Disclosed embodiments include apparatuses, systems, and methods for providing a sound indicative of a pressure of a tire relative to a target pressure. A target pressure specifier is configured to specify a target pressure for a tire and generate a target pressure signal indicative of the target pressure. A pressure monitor is configured to receive the target pressure signal, a current pressure signal indicative of a current pressure of the tire, and an indicator of a deliberate change in the current pressure and compare the current pressure signal with the target pressure signal responsive to the indicator. A status signal is generated indicative of a status of the current pressure signal relative to the target pressure signal. An audio generator is configured to receive the status signal and to generate a sound audible outside of the passenger compartment of the vehicle that is indicative of the status signal.

Abstract: This is a tire pressure warning system that can be easily installed as an after-market item. The alarm can easily be heard while the vehicle is underway. The shatterproof window of the pressure gauge exposed at the center of the wheel cover enables the driver to quickly check pressure. An adjusting screw on the pressure gauge selects the pressure at which the alarm will sound.

Abstract: A tire deflation warning device having an arm carried by the rotating wheel and normally held retracted by a plunger activated by tire air pressure. Upon deflation the plunger releases the arm to be moved radially outwardly by centrifugal force so as to contact an element on the vehicle body and sound an alarm.

Abstract: A low pressure warning cap for a pneumatic tire air valve including a generally cylindrical body having first and second ends, a cylinder adjacent the first end, a threaded connector for attachment to a conventional air valve stem of a pneumatic tire at the second end and an acting chamber connecting with and disposed intermediate the cylinder and the threaded connector, a piston disposed in the cylinder and resiliently biased toward the acting chamber, the cylinder having an opening at the first end, a deformable diaphragm disposed across the acting chamber between the threaded connector and the enlarged end, a perforated diaphragm disposed across the cylinder adjacent the opening, an elastic sack enveloping in air tight manner the first end including the opening, and a protuberance in the threaded connector to cooperate with the valve to open the valve upon attachment of the cap to valve, whereby, at a desired tire pressure, the deformable diaphragm is deformed by air from at the desired pressure to move the piston against the bias into air-tight engagement with the body to prevent passage of the air into the cylinder and, upon the occurrence thereafter of an undesirably low tire pressure, the piston is biased against this undesirably low air pressure to allow the air into the cylinder past the piston to pass by way of the perforated diaphragm and opening to inflate and rupture the sack to provide an audible indicaton of the undesirably low tire pressure.

Abstract: Excessively high or low tire pressure is detected automatically with a warning signal generated for the operator. A device is attached to each wheel and includes a spring-loaded piston mounted for reciprocation in a cylinder formed in the device. The cylinder is provided with a porting arrangement which opens only at certain pressure limits. When the ports are opened a sonic or ultrasonic signal is generated and detected by sensors located in proximity to each wheel. The signals detected by the sensors are processed and utilized to actuate a warning signal that provides a visual and/or audio output for the operator. Means are provided for discriminating between background noise and the generated signal as well as to discriminate as to the location of the affected tire. In a modification of the invention, a reserve chamber is integrated into the body of the wheel and is adapted to replenish automatically air lost from the tire.

Abstract: A system is provided for use with various types of vehicles employing pneumatic tires to signal the operator that the tire pressure is beyond a preset range. A spring-loaded pressure responsive piston is adapted to reciprocate within a valve structure in response to changes in tire pressure. If the piston is displaced one way or other beyond the predetermined range, air is released to operate a whistle detected by a sensing system on the vehicle which, in turn, generates a signal for the operator.
Abstract translation: 提供了一种系统，用于与使用充气轮胎的各种类型的车辆一起向驾驶员通知轮胎压力超出预设范围。 弹簧加载的压力响应活塞适于响应于轮胎压力的变化而在阀结构内往复运动。 如果活塞以预定范围以外的方式移动，则空气被释放以操作由车辆上的感测系统检测到的哨子，其又为操作者生成信号。
