摘要：
A filtration system upstream of a pump inlet is provided. The filtration system comprises: a first section (Figure 8A) having a first surface (112, Figure 8A) with a first array of fingers (114, Figure 8A) extending in a first direction (118, Figure 8A); and a second section (Figure 9A) mountable to the first section and having a second surface (122, Figure 9A) opposed to the first surface with a second array of fingers (124, Figure 9A) extending in a second direction (128, Figure 9A). Mounting the first section to the second section forms a fluid flow path 136 between the first and second surfaces. Mounting the second section to the first section results in the first array of fingers interdigitating with the second array of fingers, the spacing between interdigitated fingers 134 being narrower than the spacing between adjacent fingers of either of the arrays of fingers across the whole of the fluid flow path 136.

CLAIMS
1. A filtration system upstream of a pump inlet comprising:
a first section having a first surface with a first array of fingers extending in a
first direction; and
a second section mountable to the first section and having a second surface
opposed to the first surface with a second array of fingers extending in a second
direction substantially parallel to the first direction,
wherein mounting the first section to the second section forms a fluid flow
path between the first and second surfaces, and
wherein mounting the second section to the first section results in the first
array of fingers interdigitating with the second array of fingers such that the spacing
between adjacent interdigitated fingers is narrower than the spacing between
adjacent fingers of either the first or second arrays of fingers across the whole of
the fluid flow path.
2. A filtration system according to claim 1, further comprising:
at least one protrusion from at least one of the first or second opposed
surfaces,
wherein mounting the first section to the second section forms at least one
barrier projecting from a lower surface in a direction opposed to gravity across the
whole width of the fluid flow path.
3 A filtration system according to claim 2, wherein the barrier is configured to prevent
particulates within the fluid of a first size reaching the interdigitated fingers. 4. A filtration system according to claim 2 or claim 3, wherein the barrier has an
arcuate cross-section.
5B, A filtration system according to any of claims 1 to 4, wherein the first direction is
substantially perpendicular to the first surface.
6. A filtration system according to any of claims 1 to 5, wherein any of the first or
second arrays of fingers have a regular spacing between adjacent fingers.
Z. A filtration system according to any of claims 1 to 6, wherein any of the first plurality
and second arrays of fingers form a line substantially perpendicular to the fluid flow
path.
8. A filtration system according to any of claims 1 to 7, wherein the interdigitated
fingers form a line with respect to the fluid flow path.
9. A filtration system according to claim 8, wherein the line is a convex arcuate line
with respect to the fluid flow path.
10. Afiltration system according to any of claims 1 to 9, wherein the second section is
detachably mounted to the first section.
11. Afiltration system according to any of claims 1 to 10, wherein any of the first or
second sections comprise at least one side wall that is substantially curved. 12. A haptic feedback system for a pump comprising:
a housing having at least one touch sensing surface;
a pump motor contained within the housing;
a sensor unit contained within the housing having a touch sensor adjacent
to the touch sensing surface to detect a user contact; and
a microprocessor connected to the pump motor and the sensor unit,
wherein the touch sensor is configured to send a detection signal upon
detection of the user contact, and
wherein the microprocessor is configured to receive a detection signal from
the touch sensor and operate the pump motor in a predetermined manner whereby
to vibrate the housing and provide haptic feedback to the user.
13. A pump feedback system according to claim 12, wherein the motor operates in a
pulsed manner to indicate detection of the user contact at the touch sensing
surface
14. A pump feedback system according to claim 12 or claim 13, wherein the touch
sensoris a capacitance sensor or a resistance sensor.
15. A pump feedback system according to any of claims 12 to 14, wherein the sensor
unit is a water level sensor.
16. A pump feedback system according to claim 15, wherein the water level sensor is a
capacitance sensor or an ultrasound transceiver.
17. A pump feedback system according to any of claims 12 to 16, wherein the sensor
unit further comprises a light emitting diode which illuminates in response to
receiving the touch signal or any of denoting the initiation, progression or
termination of a pump motor operation in addition to the haptic feedback provided
by the pump motor.
