    摘要： A heating pad controller is provided which varies the duty cycle during which power is applied to a heating pad heating element. In one embodiment according to the present invention, an oscillator circuit is used to vary the off-time of the duty cycle, with the on-time portion being fixed. User control of the off-time is provided by way of a rotary control knob connected to a potentiometer. The potentiometer is part of the oscillator circuit and is used to vary the resistance through which a capacitor in the oscillator circuit charges up. The output of the oscillator circuit is used to control the gate of a silicon controlled rectifier (SCR), which acts as a power switch through which power is applied to the heating element. During power up, the oscillator circuit is overridden and a continuous control signal is applied to the SCR to provide constant power to the heating element to thereby achieve rapid heating. In an alternative embodiment according to the present invention, a digital heating pad controller is provided to vary the duty cycle during which power is applied to a heating pad heating element. User control is provided by way of a number of switches which are used to select one of a number of operating temperatures. Additionally, when the heating pad is first turned on or when the desired temperature setting is increased, continuous power, i.e., 100% duty cycle operation, is initiated in order to rapidly heat the heating pad to the desired temperature. Similarly, when the desired temperature setting is decreased, no power is applied to the heating element, i.e., 0% duty cycle operation.

    摘要翻译： 提供一种加热垫控制器，其改变对加热垫加热元件施加电力的占空比。 在根据本发明的一个实施例中，使用振荡器电路来改变占空比的关闭时间，导通时间部分是固定的。 关闭时间的用户控制通过连接到电位器的旋转控制旋钮来提供。 电位器是振荡器电路的一部分，用于改变振荡器电路中的电容充电的电阻。 振荡器电路的输出用于控制可控硅整流器（SCR）的栅极，该可控硅整流器（SCR）用作电力开关，通过该电源开关向加热元件施加电力。 在上电期间，振荡器电路被覆盖，并且将连续的控制信号施加到SCR以向加热元件提供恒定的功率，从而实现快速加热。 在根据本发明的替代实施例中，提供数字加热焊盘控制器以改变对加热垫加热元件施加电力的占空比。 用户控制通过用于选择多个工作温度之一的多个开关来提供。 此外，当加热垫首先打开或者当期望的温度设置增加时，启动连续功率，即100％的占空比操作，以便将加热垫快速加热至期望的温度。 类似地，当期望的温度设置降低时，不向加热元件施加功率，即0％的占空比操作。

    摘要： A programmable microprocessor-controlled digital scale capable of storing profiles of multiple users and respective user-specific weight management information includes a software program executed by the microprocessor to create and store a user profile for each user. The software program also allows the generation user-specific weight control information based on the user's profile and weight, and displays the information to the user. The generated user-specific weight control information can include, for example: current weight; absolute as well as percentage change in weight; graph of the minimum and maximum weight for the average person matching the user's profile; a thirty day rolling graph of the user's weight history; information about the number of calories that should be consumed in order to either maintain weight, or lose one pound per week; and body fat measurements.

    摘要： A blood pressure cuff which, when the cuff is being applied to the patient, automatically indicates when the proper amount of tension in the cuff has been reached. The blood pressure cuff includes a tension sensor disposed on an end which the user grips, constructed of elastomeric or elastic material, including accordion-like ridges. The ridges include a graphic which is partially or substantially hidden when less then the proper amount of tension is applied to the blood pressure cuff, and which is substantially viewable when the proper amount of tension is applied to the blood pressure cuff. The tension sensor may include an indicator area which is substantially hidden by a set of folds until a pre-set amount of tension is applied.
