Definitions
- the invention provides a novel microprocessor-controlled actuator which bounces a baby bouncer system at soothing frequencies that are optimized for the weight of a baby supported in the baby bouncer system bed.
- the invention also provides a novel baby bouncer system which includes the novel microprocessor-controlled actuator.
- the microprocessor based control system which controls the bouncing motion of the actuator also emits soothing sounds.
- a baby bouncer system comprises a cradle-like seat that supports and rocks a baby in a seated or prone position and a resilient metal frame that includes a base adaptable for support by a relatively uniform surface and an angled segment which extends upwardly to support the seat. The angled segment may be bent downwardly toward the base portion of the frame to provide a gentle rocking movement.
- the general configuration and design of baby bouncer frames and seats are well known. See, e.g., United States Patent Nos. 6.594,840 and 5,269,591.
- Bouncer support frames are spring resilient systems. Thus, the frame will bounce effectively and naturally if subjected to a bouncing rhythm which approximates the baby bouncer's natural frequency.
- the natural bouncing frequency of a baby bouncer varies depending on the weight of the baby supported in the bouncer seat. (The average weight of a baby varies from around six to around twenty-four pounds).
- a baby bouncer would preferably bounce at a frequency of from about 70 to about 100 times per minute.
- a properly designed spring-resilient bouncer support frame system would bounce at a natural frequency from 60 to 100 times per minute (approximately 1 Hz to about 1.7 Hz) for baby weight ranges of from about 6 to about 24 pounds.
- United States Patent No. 6,629,727 discloses an infant carrier having a bouncer mode of operation in which the bouncer mechanism establishes harmonic vibration.
- the carrier of the '727 Patent vibrates at a high frequency and the bouncer mechanism generates a low-level force.
- the invention provides a novel microprocessor-controlled actuator which bounces a baby bouncer system at soothing frequencies that are optimized for the weight of a baby supported in the baby bouncer system bed.
- the invention also provides a novel baby bouncer system which includes the novel microprocessor-controlled actuator.
- a microprocessor-controlled actuator of the invention comprises:
- a DC electric motor which (i) is connectable to a power source, (ii) is in electrical communication with the microprocessor based control system, (iii) during operation receives a supply voltage at a level which is regulated by the microprocessor based control system, and (iv) is enclosed within and supported by the housing;
- a speed reduction mechanism which comprises an axial shaft connected for rotation to and driven by the DC electric motor and which is enclosed within and supported by the housing;
- a rotatable eccentric weight which is mounted coaxially on the speed reduction mechanism axial shaft for rotational motion to generate centrifugal force and which is enclosed within and supported by the housing; wherein the microprocessor based control system is calibrated to maintain the DC electric motor supply voltage level at a value which is optimized to maintain baby bouncer system bouncing at a soothing frequency, e.g., about 1 to 2 Hz.
- the speed reduction ratio of the speed reduction mechanism is preferably set such that the rotational speed of the actuator's eccentric weight is from about 50 to about 100 times per minute at a microprocessor-controlled DC electric motor supply voltage range of about 40% to about 90% of the maximum motor supply voltage.

- the actuator speed approximates or matches the natural bouncing frequency of the baby bouncer system supporting a baby
- the bouncer system will bounce effectively at the baby bouncer system's natural frequency (resonance). If the actuator speed does not match the natural bouncing frequency, irrespective of whether it is faster or slower than such frequency, the baby bouncer system supporting a baby will not resonate and will either exhibit a low frequency, intermittent bouncing motion or no bouncing motion at all.
- the microprocessor based control system is calibrated by a method comprising: (1) identifying and storing motion sensor signal frequency values (Fn) over a range of DC electric motor voltage supply levels (Vn); (2) comparing stored Fn values and identifying the maximum motion sensor signal frequency value (Fmax) and the DC electric motor voltage supply level at Fmax (V of Fmax); storing V of Fmax.
- a baby bouncer system of the invention comprises: (a) a resilient support frame adapted for positioning on a relatively level surface; (b) a cradle-like bed attached to and supported by the frame in an elevated position suitable for stable support of a baby; and (c) a microprocessor-controlled actuator of the invention, wherein the actuator housing can be mounted for transmission of bouncing forces on the resilient support frame.
- the microprocessor based control system which controls the actuator also contains a voice and melody-recording and playback microprocessor which generate signals translatable to soothing sounds which, through a transducer or other appropriate device, are emitted synchronously with baby bouncer system bouncing.

- Detected motion sensor signal values Fn are recorded 108 during the period of time t.
- Voltage is tested 110 and if voltage does not equal minimum voltage Vmin (e.g., 40% of Vmax), Vn is adjusted 112 to Vn+1, where Vn+1 equals Vn - "v", where "v" is a small voltage increment which in preferred embodiments ranges from 0.1 volt to 0.5 volt, most preferably about 0.2 volts, and the actuator is again run 106 for time period t and motion sensor signal values Fn are again recorded 108 during the period of time t. This procedure is repeated until Vmax is determined, within an acceptable tolerance, to equal Vmin.
- Vmin minimum voltage
- Vn starts from a "high" voltage supply level (for example, about 90% of the maximum power supply voltage) and decreases incrementally to a "low” voltage supply level (for example, about 40% of maximum power supply voltage) , wherein each increment of decreasing voltage level is about - v.
- Vn starts from a "low" voltage supply level (for example, about 40% of maximum power supply voltage) and is increased incrementally to a "high” voltage supply level (for example, about 90% of the maximum power supply voltage), wherein each increment of increasing voltage level is about +v.

- eccentric weight 29 rotates and swings in a pendulum-like rotational movement, it generates a centrifugal force in a direction away from the center of its rotating axis. This force will pull down or push up a bouncer seat (not shown) when eccentric weight 29 rotates to its lowest and highest positions, respectively. Since the centrifugal force is always directed in a radial outward direction, when eccentric weight 29 swings to positions other than a vertical position, a horizontal force component is generated. When the actuator is mounted on a baby bouncer frame, the friction between the bouncer frame foot pads and supporting surface will balance the horizontal component of the centrifugal force.
