  • Publication number: 20040224271
    Abstract: A cake shield is provided to ensure against contamination during candle extinguishing. The shield is a thin, preferably clear (to expose the icing of the cake) and disposable layer of plastic or paperboard which is preferably provided with a window for the candles to pass through. The window facilitates the placement and removal of the candles after extinguishing the same. The cake shield is preferably sufficiently large to protect much of the top and iced surface of the cake from germs during candle “blow out” and from saliva, also during candle extinguishing. The thin flat layer of the cake shield is supported by small, preferably integrally formed, legs which gently touch upon the top surface of the cake. After the candles are extinguished and removed, the shield is easily removed and the entirety of the device is discarded. The cake shield can be decorated or shaped to correspond to the occasion being celebrated or may be entirely plain to allow the icing to fully being exposed.

  • Patent number: 4951032
    Abstract: A crib rail safety monitor alerts a child's attendant to the potential injurious situation when a child is located within a crib and the crib side rail is in the down or lowered position. Preferably, a flashing light will first alert the attendant to the condition without awakening the child. If, however, the attendant leaves the vicinity of the child's crib, with the child within the crib and the crib side rail lowered, then an audible alarm is activated. The crib rail position indicator can be an ordinary magnetic reed switch, the mechanism to indicate the presence of a child within the crib can be a weight sensor and the attendant's presence or absence can be performed by an ultrasonic motion detector or an infrared temperature sensor. Timers can be electrically interconnected with the components to ensure the child's safety while, at the same time, allowing the attendant the opportunity, before the audible alarm is activated, to remember to raise the crib rail prior to leaving the vicinity of the crib.
